Watch Tracker is a revolutionary app for tracking the accuracy of a wristwatch. It's dramatically easier and more accurate than any previous method.
Just tap a button when the time on your watch matches the time displayed by the app, and Watch Tracker does the rest. It synchronizes with an atomic clock, measures and records the difference, and displays graphs of all the data points you've recorded.
- Uses best-fit analysis to accurately calculate how many seconds your watch gains or loses per day
- Displays graphs of rates and variance
- Can track multiple watches simultaneously
- Saves data in CSV files that can be opened with any spreadsheet software
Watch Tracker is made by the developer of tChess (the chess app that was featured in Apple's "Learn" commercial for the iPad) and Learn Chess (the Apple Staff Favorite e-book).
Intuitive, useful, fun, simple, reliable, not trying to sell you any other things or ask you to “create” an account. Love it!

WatchTracker’s approach to measuring a movement’s in-case/on-wrist accuracy over time is the best. I’ve tried all the other apps for logging time, using the microphone, and purchased a timegrapher. The simplicity and ability to measure real world accuracy on-wrist puts this app above all. Regulat…
