### 5/5 — My Perfect Watch Setting App

*2023-06-18*

I have a Casio F-91W that frequently loses it’s time, and this app is a perfect godsend for retiming it. No adds, simple UI, 10/10.

### 1/5 — System requirements

*2023-06-10*

System requirements are a joke. An app that deals with mechanical watches, a fairly relaxed, a bit outdated, classical field that requires newest iOS while not providing any really heavy software features is no good. Looks like a lazy and not too bright development.

### 5/5 — Very Nice

*2022-06-04*

A very nice minimalistic app that does exactly what it claims.

### 4/5 — Simply superb. Near perfect.

*2021-04-09*

App is very clear, easy to use, and has useful complications. 
My only wish would be to have the list of cities for the GMT complication be arranged alphabetically by city name, only. Users are more likely to know the name of a city nearby their alternate location than to know which continent the developer chose for it.
