### 5/5 — What Time is It?

*2025-11-09*

Time to make sure your watches are telling you the truth. Great app for cataloging multiple watches, their wear time, accuracy, and other details. 

Also includes time check reminders, and the most elegant time setting/logging mechanism I’ve seen. 

This app needs more exposure. It’s great.

**Developer response:** Thank you for taking the time to review. I appreciate it a lot. 

Great reviews like this help with the exposure; and, of course, tell your friends :-)

### 5/5 — This is now my go-to watch accuracy app

*2022-05-05*

I tried a number of watch accuracy apps on the App Store with mixed success. Some look very pretty but don’t work so well, others work great but are not very intuitive to use. This one strikes a good balance between intuitive use, clean graphics and functionality. I also like that I was able to import data from some of the other apps I’d used with a bit of basic spreadsheet formatting.

I noticed that this app didn’t directly use an atomic clock to set the time independently of the phone but I don’t think this causes a problem. 

Overall, does a great job and now this is my go to watch accuracy app.

**Developer response:** Thanks very much for the feedback. 

On your point about the atomic clock. It was decided that having the app synchronising to an atomic clock was overkill. This is because pretty much everyone has the clock on their phone synchronised to the internet’s atomic time source automatically.

Thanks for the review!

### 1.2 — 2025-09-15

General tune up for ios26 with a new Liquid Glass app icon plus a number of smaller changes to make the app experience better overall. 

Check Accuracy screen:
- Added new cancellation process for the time check; drag your finger down to the new cancel button to abort
