Hello,
I've developed a very simple Android app to monitor the budget of your crypto. I decided to do it because I couldn't find anything that would allow you to add coins in a few steps and immediately see the value (taken from CMC) in EUR or USD (all the applications I tried also required the inclusion of the purchase date, the price at which you had purchased coins and other data).
Once a coin is added to the app, you can remove it with a simple swipe to the left or modify the amount simply tapping it.
