### 1/5 — Molar ratio calculator can’t use decimal point!

*2018-06-28*

And it freezes up constantly.

### 2/5 — Fix the Keyboard

*2016-09-20*

This is a great app. Really practical. I have been using this for a while and noticed a problem with the keyboard on my old phone. The decimal (.) does not work! I nearly broke my screen trying to enter 1.2. I thought it was just that phone but I have installed on a new phone and it's the same. Please fix this. It's irritating
