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).
- Watch Tracker now gracefully fails over to your iOS device's internal clock if there's a problem downloading the atomic time.
- The overall accuracy of a watch (according to all of its timing runs) is calculated and displayed at the bottom of the list of timing runs.
- There's a new option to display the overall accuracy of each watch on the main screen.
Ratings and Reviews
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.
A must have for wristwatch appreciating folks
Watch Tracker is a great little app. I own multiple mechanical watches and Watch Tracker is a great app for discerning the timing rate of each of my watches. No crashes, works well, and is easy to use. The graphs are easy to read, and the variance calculation and rate calculation are great features.
My only suggestion is to add a little color, perhaps bring the Description field up a level such that it is in the watch’s main screen, and maybe an archiving feature for the watches I don’t own/track anymore. These are piddly app addition suggestions because the Watch Tracker’s main functions are flawless.
Update: love the comments section and default comment drop down menu. Can you add to the menu "face up Overnight".
With Family Sharing set up, up to six family members can use this app.
