Love it!

I’ve been using this app for years to keep track of all my watches. I can easily see if they’re running fast or slow and change the position I leave them in at night to “regulate” them. A watch nerds dream.
Thank you!!

Very accurate

I’m very pressed on how a accurately this apps tracks my watch, well done.
I just wish the UI would be a bit nicer and more intuitive

Works great

Intuitive interface. Much better than the other apps i tried

Was a great app until the data corrupted

I've been using this app for almost 2 years, and randomly I lost all my data. Unfortunate, it was interesting to see how accurate some of my watches were over the years. I'll still use it because it works well for tracking watch health, but I won't count on that long term data (the cloud had the data corrupted as well)

Still the Best After All These Years

I’ve used this app for many years. The last review I wrote—also many years ago—no longer appears on the review list. I actually love this app so much that I’m writing another review to compliment the developer and to explain why some reviewers, although in small numbers, may have found the app inaccurate or hard to use.

This app is not a timegrapher that gives instant readings on your watch’s rate. Instead, it collects data points by having you match your watch’s time to the app’s time (or atomic time). Using at least two reference points, the app then calculates, graphs, and tracks your watch’s rate. You can start a new time run anytime you adjust your watch, and you can also track multiple watches with the app.

The only real requirement for accuracy is having quick reflexes—because you need to tap the screen when your watch shows the exact time displayed on the app. If you can’t tap within about 0.2 to 0.5 seconds of the shown time, the results might not be as accurate or meaningful.

Whether you’re a casual collector or a serious watch enthusiast, this app is a must-have if you care about tracking your watch’s accuracy over time. It’s easy to use and gives you detailed insights into how fast or slow your watch is running—something any watch lover will appreciate.
