Hi everyone! 

I would like to share with you all my Android apps made for making the life of Poloniex and Bittrex's users easier!

With the apps you will be able to:
- See the price of all coins in the exchange in BTC and your local main fiat currency (it already supports USD, BRL, JPY, and others. Didn't find your fiat in the app? Contact me and I'll add for you)
- Create alerts for the prices of the coins.
- See details of each coin, including order book, charts (candle and market depth).
- Internal calculator of each coin for btc and the fiat currencies.
- Pin the price of your favorite coins for reading directly in the notification bar, without needing to open the app.
- Create nice widgets for follow your coins directly in your phone "desktop".

If put your API keys (no needed for using any feature above):
- Get notified when any balance change in your account.
- See your total balance in BTC and your preferred fiat currency.
- Create and cancel orders directly from your phone.
- All of it with security, including a pin to access and fingerprint auth for available devices. And, logically, withdraw permission no needed for anything,

Some prints here (Bittrex's app, but the Poloniex's one is almost identical): https://imgur.com/a/M8DEy

Together, the apps already have more than 140k downloads around the world with about 10k unique users daily (and growing! ), it with an excellent evaluation in Google Play and it's totally free.
