### 1/5 — Poorly Designed App

*2021-08-27*

This app is poorly designed. Basic instructions are to turn the “outer wheel” of a confusing circular graphic but nothing happens. What they don’t tell you is you have to select a filter first and then you can make adjustments. Just lazy.

### 1/5 — Doesn’t work on iphone xs
