What is it?

Bitcoin Checker is an Android app avilable for free on the play  store. It offers notifications for different cryptocurrencies at  different exchanges. 

 You can enable alarms for when the price reaches a specific point, aswell as if it raises/drops for certain %.
I especially like the notification bar feature which shows you the live prices for all coins you selected. 

 Final words

I think It's a very good app that saves you lots of time when looking for live prices of alt-coins.
