Great app
Fun and easy way to track the accuracy of your watches. Not as accurate as using timegrapher but then we are talking about mechanical watches here anyways.
Fantastic
This app is fantastic for keeping track of your watches over a longer period and is much better than using a time graph which doesn’t give you a full picture
Simple to use
This is a great app - straightforward to use and easy to understand, with lots of great features such as exporting the data. Recommended. Edit: would be really useful to sync across devices!
What a fun amazing app!
So glad I found this! I think the take a photo option is pretty cool too. I hope the developers keep updating this app and continue to evolve it! Look forward to seeing what else they do! I paid for the full version so worth it.
Great app for mechanical watches
I paid $1 for unlimited access and once I figured out how to use it, it became an app I use daily to measure my automatic watches. Simple but gets the job done!
Excellent!
Dear Mr Hieu You have created an easy to use and tremendously helpful app which I use when regulating my watches. It would be fantastic if you could consider saving the data to icloud, allowing users to synchronise data on both iPhone and iPad to make measurements, as well as keeping data backed up safely. Best regards.

As an enhancement request: I find the additional 15, 30, and 45 second timers useful but too small - it’s a bit hit or miss when I attempt to use these as my finger often misses them because I’m staring at my watch dial in an attempt to press the app button at precisely the right time. Could these buttons be made to be twice their current height? There’s loads of screen area available. Thanks for considering!

Great app but freezes quite often
It is a great app, very user friendly, as the operations are intuitive. However, it freezes quite frequently at loading, and the only way to unfreeze it is to restart the phone. Hope this issue will be resolved with future updates.
Perfect
This app is exactly what I was after. I gladly paid the £0.99 to unlock the full version, these days with subscriptions or huge one off fees, this app is an absolute bargain and does everything I need it to do. Well done Hieu Pham, and thank you.
Easy way to track accuracy of my mechanical watches
Twelve is simple to use and track the accuracy of your watches. It’s a great app and I hope that it continues to be supported.
Practical and we'll designed
Stumbled across this via a Reddit pos. This app deserves more attention. Should be the gold standard for accuracy tracking. Has a very simple and well thought out interface, dark mode, etc. Great way to show off your collection too.
