### 2/5 — Was enjoying the app - unusable on iPhone 13 Pro Max

*2022-01-27*

The app seems to be inverted from how it should be on the iPhone 13 Pro Max. Top bar is white, the buttons are black, and in the calculator the backdrop is white and the blanks are black, with the labels for what is calculated where being illegible. Useful app on my old phone.

### 5/5 — Leaders in the field

*2017-05-17*

Great app.
