Description

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

Version 1.1.5

- Added support for the iPhone X
- Added the ability to customize the default data point comments
- Fixed an incompatibility with iOS 11 that was making the "export graphs" feature crash
- Added the accuracy of the best-fit rate to the Offsets graph
- Added the most recent offset to the Offsets graph

Solid App

Well-designed, just like my watch :)

This app omits questionable features such as ‘magnetism detection’ or calculations made from audio recordings of your watch.

Instead, I would call this app a (very user-friendly) specialized calculator. The time source it synchronizes with is quite good.

Although a spreadsheet is capable of doing the same math, this app is worth the money (in my opinion) because of a specific feature: a button that will instantly record atomic time when pressed. Pressing this button also simultaneously records a predetermined hh:mm:ss. The user plugs in some time in the near future and presses the button when their watch reaches that time.

Therefore, each data point contains two pieces of information from that instant: standard time and your watch’s time. This operation would be difficult to perform without a specialized program. Another method might be to use a high-speed camera that takes a picture of the watch next to some time standard. However, processing this data would require more time as the watch reading would need to be interpreted from a picture. I like this app because you can press a button and then bam, it’s done and it’s even calculated averages including all your previous data points :) very well done app

Very useful tool

I have been using WatchTracker for a few months now, and find it to be a valuable tool for tracking the accuracy of both mechanical and quartz watches. Particularly in the case of mechanical watches, being able to spot and document a change in accuracy can be helpful in spotting and perhaps even diagnosing problems.

I have recorded accuracy data for multiple watches, sometimes with very surprising results. This app has helped to identify some really surprisingly accurate watches as well as to demonstrate a need for service for other watches.

This type of app, which merely records user-input data points, does not carry the same risk of magnetizing a watch that a timegrapher app would carry. I highly recommend this app for anyone who wears or collects mechanical watches.

So many watches so little time

Solid app

This is a great time saver for me (I have a lot of mechanical watches and I’m somewhat obsessive about their timekeeping). I have been doing my own version of this with a spreadsheet, but it means I have to open up the n.i.s.t. official time webpage and then keep one eye on that and another eye on my watch. This app is much easier because you just have to tap the screen when your watch hits a time that you specify. The app automatically compares your watch to the official time. I also appreciate the graphing and analysis that’s built in. If you want to continue to use your own spreadsheet in some capacity, you can download the data to a csv file that Excel reads directly. This is a very well done app. It cost me the price of a latte. Well worth it.
