It calculates, but the history is buggy
When I open the app and make a calculation, it does not appear in the history. If I go back to the home screen and then return to the app, my previous calculation now shows. When I do the next calculation, it replaces the info in the top tile instead of adding a tile. On the next calculation, things start working as they should. This is the pattern every time I clear the history.
I would give this app 5 stars if not for the buggy history. Without that feature it is a decent calculator, but then it is just a calculator. Please fix it for a great app!
