FoxyTrader - cryptocurrency trading terminal for Android (beta)

Dear crypto-community,

I am the creator of the FoxyTrader Android application and would like to introduce its origin, purpose, features, key differences from similar apps.

IMPORTANT

At the time of posting, FoxyTrader is in beta and supports Bittrex exchange only. It is free, without ads or in-app purchases. Link to the app on Google Play Market.

ORIGIN

I became interested in cryptocurrency in June, 2017. At that time most of cryptos out there were booming, and I was very curious and decided to buy some. Having chosen the Bittrex exchange as my entry point, I bought a few dozens of different cryptos, but that's not the point. I was wondering, how could the above exchange not have its mobile version and have overall outdated website design. Like, cryptos are cutting-edge technologies, but exchanges on which they could be traded are looking so old. I decided to start a hobby project, it's first name was TrexBit (hence the package name of the app). The Bittrex API was pretty simple to implement, so the version you can see at the moment of posting was developed in just 3 months. 

What about the FoxyTrader name? Well, as I had decided to support other exchanges in the future, I changed it to resemble it's not bound to Bittrex, and it's a trader app! And it's mainly red coloured, too. 

GOAL

Ever felt like you could miss a sudden trading opportunity while you're not at your PC or don't have your laptop at hand? The cryptocurrency market is so volatile that it's not even feasible to always catch up. FoxyTrader Android app was designed to let its users trade anywhere, through clear and neat UI.

FEATURES

Basically, FoxyTrader is an ultimate mobile trading machine. It (almost) fully resembles current Bittrex features, plus useful price alerts and even wallet actions notifications, and more.

Full list of features, as per Google Play Market listing:

• Full list of markets, separated by base currency. Ability to search by full or symbolic name and sort by volume, price, change, name, last trade, added date.
• Logging in using the API keys. Required to do account-specific operations. Ability to add additional password protection when you log in.
• Your open and closed orders. Ability to search by full or symbolic name, date and sort by date, name, cost/proceeds, units. Ability to see price change since order placement Requires logging in.
• Limit trading. Auto bid/ask field population until you interact. Bid/ask suggestions on the fly. Possibility to fill in your available balance. Auto-calculate cost/proceeds. Requires logging in.
• Wallet management. See your balances, deposit and withdraw. Currency distribution pie chart. Ability to search by full or symbolic name and sort by value, name, units or change. Withdrawal and deposit history with detailed data. Requires logging in.

• Price alerts with history.
• Order execution and wallet actions notifications.
• Night mode.
• Support for 32 different fiat currencies.

DRAWBACKS

1. High data usage. The app interacts with the Bittrex exchange directly. This means I cannot design the perfect API that would fit the app's needs on my own server, and I couldn't "reject" some useless parts of data Bittrex API responds with.
2. Bugs? I'm just a single person with one physical phone. I couldn't test the app on different devices to prevent bugs specific to them.

Feel free to add app's problems in the comments section.

KEY DIFFERENCES FROM COMPETITORS

1. Design. That's what FoxyTrader is about.
2. There is no middle-man server (actually I simply can't afford one + developer for it). All requests are done directly through exchange API. This effectively means that only the app and the Bittrex SSL servers see the API keys.
3. Encryption + Android Keystore protection for API keys and additional passwords. As the app has to save them, it must make them secure. For that I use this library.
4. Ability to withdraw funds. More info in the next section.

ABOUT WITHDRAWALS

The app provides withdrawals functionality unlike any other app I see at the moment of posting on the Android market. Well, as the first user of my own app, I find the withdrawals useful for myself. The overall process is like 50x time faster than logging into Bittrex site, waiting a "can't-withdraw-after-logging-in-delay" and only then withdrawing. Using my app I can do that in literally seconds.

By having added that functionality, I am not pushing anyone to enable WITHDRAW permission on their API keys. And if you still enable it, you're the only one responsible for your funds safety. No one can guarantee 100% security. 

CONCLUSION

FoxyTrader was made to let people trade cryptos on their mobile devices efortlessly. The app is fully free, so I hope you consider it as my contribution to the crypto community. If you would like to thank me in terms of crypto donation, you could find the respective section at the bottom of the settings screen.  Finally, a few screenshots of the app:
