This app has kept me updated on the cryptocurrency news and market for a long time now, and it is the greatest app for staying well-informed. It's free with no fees guaranteed. You can choose which trading platform you want to track(Bittrex, Binance , etc. )The graphs are refreshed in real-time. And lastly the new update just added the ability to track your crypto by alerts of which currency you have. Overall a phenomenal app Excellent app and excellent support
