Twelve O'clock

This is a simple, yet reasonably accurate, way to gauge the accuracy of your watch without using a timegrapher. I highly recommend.

For tracking watch accuracy, this app is simple and works exactly as it should. Not sure about the camera sync function as I don’t use it, but for tap tap it is very intuitive and the app itself is modern and clean.

Really nice implementation of how to track accuracy of your watch. User interface is so intuitive and has the functionality need to track progressive baselines. Fantastic work and well recommended!

I’ve been using this app for a few years now. It’s great. Simple and easy! If I could make one suggestion, it would be to show the year data along with the month/date so that when looking back through the checkpoint history it would be easier to see what’s what.

This app works great and is tremendous value at only $0.99. Only issue I’ve run into is with the graph display, which I do really like. Sometimes after a check-in the graph display will kind of bug and not show the most recent check in and the lines will shift in a weird way. Otherwise though no issues at all

I got this app since the developer is also a Watch enthusiast and listens to his customers. He updates the app very frequently, proving that this app will only get better. Worth the .99cents to fully unlock the app to have multiple watches tracked, and see which ones are out of spec. Also, I like how you can sort the watches in order from highest or lowest accuracy and how you can check the time at 15s, 30s, or 45s mark instead of waiting for it to reach to 0. Great job. Looking forward to more updates.

I’ve used this app for several months and enjoy the simplicity.

Does all the basic tracking and charting you need to keep an eye on watch health. Well worth buying the upgrade just to show appreciation for nice addition to watch collectors tool kit.

I got this app to try as an alternative to Toolwatch. I never use that anymore. I find this much more intuitive, easier to use, and providing a more practical record of my watches’ accuracy.

You can tell the developer is a user of the app himself, as everything is simple, well described, and very well executed. Fantastic app. Rare to find one like this! Love the FAQ section where he talks a bit about his life and how the app works.
