### 5/5 — Old devices

*2026-08-14*

I used to use this app on old iOS devices and it would be great if it was still compatible with iOS 3 and up- in 2026 lol

**Developer response:** You're right, that would be wonderful :) The app actually ran on the very first iPhone. Those were the good old days :) Unfortunately, today it's practically impossible to continue supporting such old OS versions, due to the lack of support for them in newer versions of the development tools. Still, it's nice to look back and reminisce :)

### 2/5 — Bildschirm drehen funktioniert nicht

*2024-12-06*

Sonst super nur and der speichergröße mängelts

**Developer response:** Dieses Problem sollte in der neuesten Version behoben sein.

### 5/5 — Catch

*2024-04-06*

Hatch

### 3/5 — Wonky

*2024-04-03*

It doesn’t do well with an iPhone SE 2020 that has auto rotate function.  It glitches out when rotate horizontal showing black lines on the side and when rotate back to vertical, it is in the shape of the horizontal until you reset the app and everything is back to normal.  Whenever you rotate the clock, horizontal has issues.  Originally default vertical no issues, but under horizontal then flipping to vertical, you will see

**Developer response:** The rotation issue has been fixed.

### 5/5 — Update

*2023-01-07*

Brak jakiejkolwiek aktualizacji, zapomniana aplikacja- taka szkoda bo aplikacja jest bardzo fajna. Lack of any update, forgotten application - such a pity because the application is very cool.

**Developer response:** W najnowszej wersji błąd ten został naprawiony.
