Watch Tracker is a revolutionary new 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).
What's New in Version 1.1.2
- Updated the atomic clock code to support IPv6
(It was displaying "Error" in some cases.)
Great and recently got better
I've used this for over a year to periodically check my mechanical watches. Recent upgrades are amazing to the UI and I love it even more!
Helpful to track the performance of automatic watches. Easy to use.
Very useful and thoughtfully designed
I was pleasantly surprised by the thoughtful design of this app. Adding data points is easy as the app automatically suggests a time in the next few seconds and has you tap a single large button when that time appears. The graphs are useful, and the app allows for multiple timing runs (after adjusting the time on your watch). Easily worth $5 and I can't really think of any way it could be improved.
