### 1/5 — Doesn’t show any value on the bottom

*2020-10-01, version 1.0*

Whole bottom line is missing on iPhone X iOS 14 and can’t see any value. Makes the app useless. Sorry

### 4/5 — Nice and simple

*2020-02-24*

Works great. Only improvement I could think of would be to add numbers into the color buttons to help with remembering the colors over time. Of course we wouldn’t need the app any more then. 😁

### 5/5 — Works intuitively, iPhone X support

*2018-07-27, version 1.0*

This app works intuitively (no need to select how many bands the resistor has) and supports the iPhone X screen. Very good, cannot complain at all
