### 4/5 — Is app still updated?

*2020-06-07, version 1.34*

I have been trying to add a custom screen size for calculations and when adding one, the save(or cancel) buttons aren't clickable. Running iOS 13.4.1, On iPhoneX. This is the main feature of the app I use and would love to have it functional again!

### 1/5 — Editing can’t be used.

*2019-09-29, version 1.34*

This app is really handy but you can’t edit or change any measurements or data input or add new screen sizes because the app hasn’t been optimised for years now. Really needs an update so you can use all the features on all iPhones.
