Review of the best Bitcoin apps on Android

This article is an overview of several applications on Androidrelated to the use of cryptocurrency, mostly bitcoins. The modern pace of life requires technological devices to be reliable and functional, and, in some cases, necessarily mobile. The most popular mobile operating system today is Android, which allows you to choose applications for her for every taste and need. As blockchain technology spreads and is introduced into everyday processes, cryptocurrency applications for Android rightfully occupied a significant segment among all others.

</p>

There are a huge number of cryptocurrency applications for Android, and not all of them are equally useful.

The Binance application for Android records conversations

Therefore, it is worth immediately limiting the range of search in order to avoid the use of any lewdness.

The review will include:

  • Wallets, including for the Lightning Network.
  • Applications for trading, as well as monitoring rates and news
  • Other applications (communication, games, etc.)

Additionally, the issues of security and privacy of devices running Android OS will be covered.

Review of the best Bitcoin apps on Android

Warning! BitNovosti editors and the author of this material are not responsible for the actions of the mentioned applications. Use them at your own risk. The information presented in the review is current at the time of its creation. Be extremely careful and careful. Avoid scammers and inadequate developers.

Promon: hackers use Android vulnerability to access cryptocurrency wallets

Honestly, I am not a supporter of usingcryptocurrencies on a mobile device. Because, despite all the efforts of the interested community, cryptocurrencies still have a rather uncertain status both in Russia and in the rest of the world. At the same time, mobile devices, mainly running such leading operating systems as Android and iOS, are completely tied to your real personality.

Phone number, mail, contacts, accounts,payment applications, camera and microphone, GPS - everything is woven into one, which connects each action with the owner of the device, as well as the actions of the owner of several devices and his family members. Only the most careful, sophisticated and competent users can avoid this (and there are few of them). Various security measures such as retinal scanners, fingerprint IDs and voice IDs (“Ok Google”) only add to the inevitable effect of control. (I always knew this, but, as I recall, it becomes uncomfortable).

Do you know what will happen if you neglect information security?

Here's an example:

</p>

therefore, the System has no sympathy for Bitcoin. At the same time, Bitcoin is alive and well, but it requires some basic precautions. For example, don't associate wallets with your real identity. Everyone knows that the deanonymization of income can end very badly, especially for the owner of the cryptocurrency.

Android is not private by default - installed applications can access data from other applications (with your permission), as well as your personal information.

In addition, the device itself may fall into the handsan intruder, a law enforcement officer, or worse, a malicious law enforcement officer. Be prudent and avoid losing your honestly earned bitcoins.

Bitcoin and Android: mixing the incompatible

In this material, we will focus specifically onusing cryptocurrency (mostly bitcoin) on an Android phone. it is the most popular and readily available open source operating system.

At the same time, Android has long turned into the mosta real "Googlephone" (as it was conceived - Google bought it out three years before the official release). And, most importantly, it allows you to spy not only on you, but also on you (which happens more often).

Although, we must admit that for the ownerThe danger of cryptocurrencies does not come from Google itself. In fact, it is necessary to protect the device from direct physical access and theft of funds by hacker methods. At the same time, it would be just good form to save the device from the excessive attention of large technology companies. Richard Stallman will certainly approve.

Can you do without Google on Android? Honestly, no. Because it's inconvenient. It's easier to limit the activity of built-in applications or remove them altogether. But, if absolute security and anonymity is required, then within the framework of this article, options for flashing the device are not considered.

Still, use an Android devicewithout a Google account you can. Whether this makes sense is up to you. In any case, mobile devices are not a suitable option for storing large amounts of money. Moreover, it is unlikely that the main danger in this context of using your smartphone / tablet is precisely Google. It is better to protect your savings and personal data from undue attention of others.

***

But, nevertheless, it will not be superfluous:

  • Disable auto-update apps from Google Play
  • Disable Google Account Sync
  • Allow installation of applications from third-party sources
  • Limit Google's collection of information about your activities

***

Cryptocurrency wallets for Android

Before installing the wallet - make sure it is not a fake. Otherwise, you risk losing your money.

To eliminate unnecessary risks - go to the office. the bitcoin.org website page and open the section with the recommended wallets:

https://bitcoin.org/ru/wallets/mobile/android/

***

A cryptocurrency wallet usually guarantees:

  • Full control over your account. Nobody can check how much money you have and freeze it if you wish.
  • At the same time, no special trust in the reliability of the transfer is required - all transactions are irreversible.
  • As a rule, cryptocurrency wallets are open source, which allows us to hope for their reliability.

***

Although, in this case, all three advantages have a downside:

  • You must take care of the safety of funds yourself (protect the device from hackers and make backup copies of wallets)
  • If you transferred money by mistake or the receiving party did not fulfill the terms of the transaction on their part, you cannot return anything and you cannot complain anywhere.
  • Open source allows not only honest developers to study it, but also malicious hackers for vulnerabilities. Therefore, do not store too much funds on the so-called. "Hot" wallets.

***

When choosing a wallet, you should pay attention to the following aspects:

  • Developers reputation
  • Security (open or closed code, method of storing keys and confirming transactions)
  • Anonymity (the need for identity verification, as well as IP encryption and hiding mechanisms)
  • Functionality and usability of the interface
  • Transaction cost (is there any additional developer fee)

***

Bitcoin wallet

</p>

Admittedly, this is the simplest bitcoin sending and receiving application imaginable. Nothing extra - just you and bitcoins.

Not only is it the first mobile wallet on the list,presented on the site bitcoin.org, but, probably, the very first bitcoin wallet on Android, development on which began back in 2010 by the famous programmer Andreas Schilbach.

***

AT progress bitcoin tour of Europe Bitnovosti had the opportunity to chat from programmer Andreas Schildbach, developer popular Android wallet Bitcoin Wallet for Android. Conversation was happening March, 3rd 2016 year on bitcoin-mitape at Berlin cafe Room77.

***

Synchronization is extremely fast. only a small fraction of the latest transactions are needed.

</p>

Security is implemented as simple as the wallet itself - an application password and a backup copy. Lost a device with a backup - lost bitcoins.

Therefore, you just need to have at hand reliable tools for encrypting and synchronizing data, in our case - backups. And no clouds!

By default, the wallet uses advancedversion of bitcoin addresses - bech32, which is part of the SegWit technology. In particular, this innovation significantly speeds up the transfer of bitcoins between similar addresses (and makes them cheaper). You can read about SegWit and its benefits here.

By the way, the presence of SegWit support is a rule of good form for any self-respecting bitcoin wallet (if we are talking about "real" bitcoins).

The commission level is set manually (three modes), however, there is no way to set a specific amount. Although, usually, the recommended value is quite satisfactory for the user.

Additional features includethe ability to connect only to a trusted node (and you can only trust yourself) and the implementation of offline payments via bluetooth (synchronization is performed later when the device is connected to the network). You can connect to certain nodes not only directly, but also through Tor.

On this, in principle, there is nothing more to say about this wallet, and you can move on to more interesting and advanced options.

If you wish, you can practice "on cats", or rather on test bitcoins. They are almost indistinguishable from the real ones, with the exception of the name.

Electrum wallet

</p>

This is already a more remarkable thing from extremelya popular brand known for its reliable and functional desktop applications for storing cryptocurrencies. Although, one is enough to work with bitcoins. It's great that the desktop client is available in a portable version, which allows you to use it directly from a secure flash drive. But, this is already material for another article.

***

Electrum wallets - light clients,which do not download the blockchain to your device, which requires them to connect to remote nodes. True, in the settings you can choose which node to connect to, including, it may be your node.

As well as the desktop version, the mobile application uses a number of addresses to receive and send coins, which significantly increases the confidentiality of transfers.

Also, from the previous wallet - Electrumis distinguished by the presence of a seed phrase for recovery from any device. However, in this case, it is recommended to take care of the safe storage of the twelve most important words in your life, for example, engrave them on metal and hide them away from prying eyes.

Another interesting feature, in addition to the default SegWit support, is the built-in interface for making payments in the Lightning network.

Lightning Network support added to Electrum wallet

For Lightning, though, other dedicated wallets will be introduced here.

Finally, it is worth noting the convenience of creatingnew wallets for use in the Electrum mobile client; and a more flexible approach to managing fees. In general, the application leaves a pleasant impression and can be safely recommended for everyday use.

But for more complex cases where maximum confidentiality is required, more functional and equally well-known things have been created.

Samourai wallet

</p>

“We are privacy activists,dedicated their lives to developing software that Silicon Valley will never create, that will never be approved by regulators, in which venture capitalists will never invest. We create the software that Bitcoin deserves and we are proud of our open source! "

Yes, after this it is impossible to pass by this project. Here, even the most sophisticated geek will certainly secretly wipe away a stingy tear.

It should be noted right away that getting a full-fledged wallet must be downloaded not from Google Play, but from the official website of the developers:

https://samouraiwallet.com/download

https://github.com/Samourai-Wallet

***

Today, Samourai Wallet, launched back in 2015, is rightfully considered the most versatile and advanced bitcoin wallet available on Android.

In order to detail all the functions andfeatures of the wallet, or rather, a whole set of software from the Samourai family - you will need to make a separate material, so only a general, brief description of the mobile client will be presented here.

Samourai Wallet features:

  • Full Segwit support for fast and low cost transactions
  • You control your private keys yourself, which are not transferred to third-party servers
  • Dynamic estimation and custom commission settings
  • STONEWALL technology to enhance the privacy of your transactions
  • Ricochet technology versus transaction tracking
  • Sending and Receiving Private Payments with PayNym (BIP47)
  • Deterministic sorting of input / output data for greater anonymization (BIP69)
  • Increased commission for a sent transaction using Replace By Fee (RBF) and Child Pays for Parent (CPFP) technologies
  • Routing outbound transactions through a trusted host
  • Addresses are not reused
  • Standardized export / import function. Backup is compatible with any other wallet based on BIP44 / BIP49 / BIP84
  • Hidden mode. To access the wallet, you need to dial the secret code on the call panel
  • Remote SMS commands to remove wallet from a lost or stolen device
  • Built-in local Block Explorer
  • Seed phrase support
  • Full client side encryption
  • VPN or Tor connection
  • Full offline mode

***

Whirlpool is worth dwelling onin more detail. Whirlpool is a completely decentralized analogue of a conventional cryptocurrency mixer (toggle switch) that works as part of the technology for anonymizing transactions - CoinJoin. The function mathematically decouples sender inputs from recipient outputs, thereby complicating the process of tracking transactions.

Anonymous coins mechanics

Thus, the Whirlpool framework is a modular implementation of CoinJoin, developed using the ZeroLink protocol, or rather its modified fork.

Whirlpool was originally only available in Dojo -a fully functional PC wallet, which is a full-fledged node equipped with advanced features and a user-friendly interface. The solution turned out to be extremely popular, and with the addition of a toggle switch function to the mobile version, Samourai caused a threefold increase in the volume of anonymous transactions in a few months.

***

Sentinel

</p>

Sentinel is the so-called. An "observer wallet" whose sole purpose is to keep track of balances and transactions, as well as create new addresses for cold hierarchically determined wallets.

According to the developers, Sentinel does not storecustom identifiers or private keys. To track an address, you just need to scan the extended public key (XPUB). You can install the application from the Google Play store or from the developer's website.

***

Exodus

</p>

Well, after all, a person is not fed up with Bitcoin alone! For those who need to work with several cryptocurrencies at once, the Exodus application offers not only wallets for dozens of different coins, but also the ability to exchange them among themselves. Scary to think, but Exodus can store over 100 cryptocurrencies and derivative tokens.

More details here: https://www.exodus.io/status/

A multicurrency wallet does not require registration or any personal data at all. Coins are freely convertible among themselves with a minimum commission (for miners). Exodus itself takes nothing.

True, like all glamorous wallets he hasthere are strange features. For example, a seed phrase for recovery is available only after depositing the first funds to any wallet address. Although, the PIN code can be set immediately.

+ closed source, which does not add value to it. The commission is not set manually - it is not for a promising blockchain to reap a penny.

Private keys are also stored on the client side, which is definitely great. The blockchain does not load - all ordinances take place on third-party servers. Although, for a mobile client, this is normal.

In general, Exodus is a beautiful and convenient wallet, without serious flaws and claims to revolution.

BLW: Bitcoin Lightning Wallet

</p>

So the turn of innovation has come: a two-in-one application that allows operations to be carried out on both the main Bitcoin network and the Lightning network.

In the best traditions of the technological underground, private keys do not leave your device, which gives some guarantees of the safety of funds.

It is worth recalling that Lightning Network technologyallows you to make instant (theoretically) payments in bitcoins, which is implemented due to the second layer (add-on) on top of the main network. You can read how it works here.

***

During installation, a new wallet and recovery seed are created. Don't forget to write it down.

</p>

In order to start using the Lightning Network, you first need to replenish the balance in bitcoins, and then open a payment channel with one of the nodes in the network.

True, a kind developer has already taken care of this, and one channel (his own) is already open by default:

</p>

Moreover, this is a difficult channel, and a hosted channel witha reserve of 0.1 BTC, which allows other users to immediately issue invoices to Lightning Nerwork (without replenishing the balance on their part). But, this is a feature of this particular wallet.

</p>

The payment link is one-time and short-lived.

***

If you decide to open channels yourself with other nodes, you will need a little theoretical knowledge.

It is important to know: you cannot receive or spend more than the amount that you sent to open the channel. Moreover, in order to receive any amount within the channel width (the invested amount), you must first spend the same amount.

Example: you need to get $ 100 via Lightning Network. You take your $ 110 in bitcoins, replenish the balance of the Lightning wallet, then open a payment channel with one of the nodes (the list is in the wallet), wait, wait again, then if the node is happy to see you, a channel for $ 110 opens.

Do not disconnect until the channel is finally open - a change in its status will tell you about it!

</p>

Each node has its own minimum to open(the maintenance of a node is expensive). If $ 110 is not enough for him, he has the right to have nothing to do with you. These sites are equal users just like you. There is no bank and no responsible persons here.

Now you must free up space to receive $ 100 - for this, withdraw $ 100 back (through the exchange office) or spend it, $ 10 remains and a place for the new $ 100.

Thus, it becomes clear that usingThe Lightning Network requires some investment. It's just worth understanding that if you just need to get $ 100, use the main Bitcoin network for this, and if you need to pay $ 2 per cup of coffee every day with a minimum commission, then use the above scheme with Lightning. If you can find where to pay for coffee via Lightning Network. I personally prefer drinking coffee at home from a beer mug.

It is important to know: receiving payments is possible only if your wallet is online. And second: your partner has the right to close the channel at any time. And if you are offline, your deposit can go to a dishonest node (although, as a rule, the funds are returned back to your bitcoin address). Therefore, only connect to known nodes.

True, here too the developer of Bitcoin LightningWallet has taken care of the user's safety. By default, a special service is already included in the wallet, the so-called. "Watchtower", which monitors your channels for violations by partners for a nominal fee.

And remember that the payment may not go through - in this case, the money will also be returned back after some time.

Additionally, once again it is recommended to carefully read everything about the features of this technology.

Applications for trading and rate monitoring

Today, everyone can easily become"A real trader" - simply by creating an account on any available exchange (on one of tens and hundreds) and replenishing the balance. Further development of the situation depends on the correct choice of the exchange and the adequacy of the newly-made "wolf of Walt Street".

For the convenience of trading various assets, you caninstall a separate application or a whole terminal in order to combine all accounts in it and use more advanced functionality, customizing it to suit your own needs.

And this is where serious problems come to light. After all, unfortunately, not everyone thinks about how safe it is to trust third-party software with their finances and confidential data (personal information, information about current and planned transactions, transaction history, balance sheet content, etc.). Critical information and access to transactions can be at the mercy of scammers (dishonest developers) or hackers. In this case, losses are inevitable for the unwary trader.

ESET: Android vulnerability targets cryptocurrency exchange users

Therefore, when working with the terminal, a trader must make sure that his information is reliably protected.

So do mobile trading apps meet basic security requirements?

Alien's free software steals money from Coinbase wallet

A number of experts have tested most of such applications long ago and the conclusions turned out to be disappointing - most did not even meet basic standards and were potentially unsafe.

The most common threats:

</p>

Even if we discard options with initially dangerous applications, which were specially created for unauthorized actions, there remains a wide vector of attacks from hackers.

To exploit these threats, an attacker needs:

  • Be on the same network with the user and havethe ability to intercept traffic. This attack is called “man in the middle”. For example, for its implementation, you can connect the user's device to a fake Wi-Fi access point or base station of a mobile operator.
  • Get physical access to the device,for example, you might lose your device or just leave it in plain sight. Yes, a PIN code is required to protect against unauthorized access to the application, but this is not a problem if the software is not protected against brute force (brute force). In some trading applications, experts have discovered the possibility of unlimited brute-force PIN-code brute-force. The counter of attempts to enter the password was reset when the application was restarted, so it was possible to select the access code as much as you like.
  • Infect the user's device with malware. This is especially effective if root rights have been unlocked on the device. As an example - third-party keyboards, which can turn out to be keyloggers, which would allow an attacker to steal authorization data in various applications.

Attention! Some Android devices can steal your bitcoins

TabTrader

TabTrader is a fairly convenient terminal fortrading on various cryptocurrency exchanges. The app tracks the exchange rate and trading volume for a wide variety of cryptocurrencies on exchanges such as Coinbase, Bitstamp, Huobi, Kraken, Bitmarket, Bittrex, etc.

</p>

Several types of charts are available in TabTrader: line, area, bars, Japanese candlesticks, heiken ashes and empty candles.

Also, you can use several different technical indicators:

</p>

You can set up instant sound notifications about the slightest change in the value of a particular asset.

It should be noted that to work with exchangesyou will need to create an account with TabTrader, which is a significant disadvantage as all your accounts will be linked together. For a trading terminal, this is normal, but unless pre-authorization on a third-party service is required, as in this case. In terms of privacy and security, this is not the best solution. Whether the service collects usage statistics and whether it can access all information in the application is unknown. [use TabTrader at your own risk].

exchange account API key, and then bind it to the terminal. When creating a key, you should not endow it with withdrawal rights. But, creating and configuring an API key is a separate story.

Finally, it is worth noting that the application contains news from such well-known resources as Reddit, Coindesk, Bitcoin Magazine, etc.

Although, there are more interesting applications for monitoring news.

Blockfolio

Blockfolio is a popular app thatworks with a huge number of cryptocurrencies (more than 8000), allowing you to create a portfolio even without a direct connection to the exchanges. Additionally, it provides news signals directly from teams of various cryptocurrency projects.

You can get detailed information on each currency: current rate, charts, depth of market, etc.

</p>

If necessary, it is possible to create alerts for a given event.

For reliability and security, it is recommended to add a pin code to the application and use the "Hide balance" function.

</p>

The simple list interface will allow you to quickly convert about 800 different cryptocurrencies and 160 fiat currencies. Simple, fast, effective.

CryptoPanic

</p>

Unfortunately, the above applications do not have a section with Russian-language news, but this is not a reason for disappointment. There are excellent cryptocurrency news aggregators like CryptoPanic.

The main feature is multilingualism. It is enough to go to the settings (swipe to the left) and select only Russian in the filter. Now you will be aware of everything that is happening in the world of cryptocurrencies. News is collected from both regular sites and threads on Reddit, YouTube channels and influential social media accounts.

Other applications

Among the rest of the applications that may beuseful for a trader, journalist or just an enthusiast, you can recommend software for accounting finance and time, various instant messengers, organizers, encryptors, etc.

I won't focus on this here, but I can't help but focus on just a first-class messenger.

Telegram

</p>

Needs no introduction. The official mobile client has become especially valuable in the form of the ability to finally scatter all the channels into separate folders and separate them from long-suffering contacts lost somewhere in between.

First: a convenient tool for communication and conclusion of transactions. Easily contact cashier, client, employer, contractor, colleague, companion, etc. And all this without the vigilant control of Google and Facebook. The application is light and fast, does not consume much battery, and is open source (client). If necessary, you can use encryption of correspondence. No trust? Better than WhatsApp, right? If not convinced - use something more confidential, for example, Antox.

One disadvantage of Telegram: registration by SMS. But whoever needs it will solve the problem, if it is. Foreign servers? I sincerely believe that you are not going to trade illegal substances.

Second: a huge number of channels, chats and bots dedicated to cryptocurrency topics. For example, you can subscribe to the Bitnovosti channel)

For example, I'll tell you about two fairly well-known bots on Telegram.

***

Whale alert monitors large transactions on eleven blockchains and reports the details of these transactions on his Twitter, as well as Telegram.

How is this useful? For example, on September 3, a bot reported a significant transaction of 60,000 BTC. This marked a sharp drop in the exchange rate throughout September. Don't believe me? Open TradingView app and check. You've already installed it, right?

</p>

Have you seen this? From April 1 to September 3, there is a clear upward trend. Phenomenal.

***

@FOMO_Bot - Provides detailed information on long and short positions, as well as derivatives and futures from exchanges such as BitFinex, OKex, CoinFLEX, Kraken and BitMEX.

And there are still a lot of such sources on Telegram - from official resources to blogs of seasoned Internet investigators. Take your pick, be impressed, shop (or run).

Ten rules and questions about security on Android

Don't search for apps on Google Play directly -look for the site's site (if possible, check its address with an additional, trusted source, for example, from Wiki) and go to the application download page from there. This will significantly reduce the risk of getting a fake app.

Phishing apps found on Google Play

Do not rush to make root - perhaps it is for youabsolutely unnecessary. By rooting a device, you risk its performance and significantly weaken security. Most of the necessary tasks, such as restricting network access for a specific application (firewall), removing / hiding applications and backing up, do not actually require root privileges.

Do not install redundant applicationsduplicating each other's functionality. Each application is an additional burden and security risk. Moreover, do not install games and pirated applications on a device where you store at least some significant funds. To test an unknown application, you can use the Android emulator for Windows. In my opinion, Nox and Andy have proven themselves the most well.

Do not download or run media files ona device that is designed to store serious amounts. Your mobile wallet should be a steel safe, not a file washer. The recommendation does not apply to users who store very small amounts on their devices for operational expenses.

Encrypt the entire device and individual apps / files. This will greatly enhance overall security and limit direct application access to other parts of the system and storage.

Do not use cloud-basedstorages such as Google Drive (and other servers from this company), Dropbox, etc. To create a backup of applications and files, you can easily deploy a server on your own PC - synchronizing devices over a mobile or local network.

Try to avoid apps with closedsource code. They are usually filled with ads or collect your personal data (or worse, they steal it for criminal purposes). It is much safer to install an additional app store, such as F-Droid, and download the apps you need from there (if possible).

Use two-factor authentication where possible. Moreover, it is not necessary to use a Google authenticator - in fact, there are many more options.

Install applications on your device thatlet you work over VPN and Tor. To be honest, I cannot imagine the further development of Bitcoin (and its existence) without these technologies. Otherwise, the whole meaning of the exclusive idea is lost. VPN and Tor will relieve you of intrusive resource blocking and hide your real IP for servers and nodes that installed applications access.

Avoid cryptocurrency mining apps atAndroid. That's bullshit. You will not earn anything and even worse will kill the device. Bitcoin mining on Android? If you have even a drop of adequacy, then such statements by the "developers" should cause nothing more than a grin.

Miner apps are available for download in the Google Play Store despite the ban

Conclusion

By and large, this material gives onlygeneral idea of ​​the necessary applications for Android, which greatly simplify the work with cryptocurrencies. But, first of all, you should pay attention to the optimization of the operating system, interface, security and trouble-free operation of the device. It is recommended to pay special attention to the chapter "10 rules and security on Android" to avoid significant problems in the future.
