### 4/5 — Not syncing

*2024-10-13*

It’s 3pm but it’s saying it’s 8, shouldn’t 3pm be 6 or 5? My location is synched correctly in the app so I’m not sure what the problem is.

### 5/5 — Islamic clock

*2022-11-07*

Is it possible to make a clock using the Islamic temporal time keeping system?

### 4/5 — Good app

*2019-12-22*

Good app, but for some reason the word “Tempōreki” doesn’t have a line above the O.
