### 3/5 — pls update

if only the app would save our favourite conversions, it would be so good!!

### 2/5 — The reverse arrows won’t work

Reverse arrows won’t work and now (5 minutes after using) I can’t even type in the bottom field

### 4/5 — Excellent interface

*2020-04-30, version 1.1*

I have previously used many converters on my phone and have been unhappy with the time it takes to locate the values I am trying to convert. The user face for this app is so easy and quick. It’s not cumbersome. Thank you for making a simple task, also a fast one!
