## What is Watch Tracker?

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).

### 5/5 — Very close to ideal

*2026-08-11*

I review apps in terms of “would I install it again?” And for this one, that’s a definite “yes”. Been using it for several years, and it makes keeping an eye on real performance variations  pretty easy. Having a timegrapher isn’t a substitute because of the stored history and stats display options.
If asked to criticise it id suggest that its a minor gripe to have no permanent display of exact present time without digging back to bootup menu. Minor? Yes. Gripe? Yep. Were this my work (I wish!!) I’d have a time reference on all screens. Why’s it so buried? Goodness knows. Fix that, for me Id consider this to be close to ideal as a tool dedicated to keeping a weather eye on watch health.
But. It does encourage you to fixate on minor fluctuations that - in a “real world universe” without digitime exactness so universal we would set our watch, put it on, and essentially forget about checks until you noted it’d drifted a touch too far from that real time reference - so you’d correct that and get on with actual LIFE instead of this silly fixating on seconds-errors being seen as excessive.

### 5/5 — A Hidden Gem for Watch Enthusiasts ⭐⭐⭐⭐⭐

*2026-08-06*

I’ve been using Watch Tracker for several years, and it’s still my go-to app for monitoring the accuracy of my mechanical watches. It’s one of those rare apps that focuses on doing one thing exceptionally well.

The interface is clean, intuitive, and free of unnecessary clutter. Tracking multiple watches, viewing long-term accuracy trends, analyzing rate and variance graphs, and exporting data when needed are all thoughtfully implemented. The atomic clock synchronization and best-fit analysis make it incredibly useful for anyone who enjoys understanding how their watches perform over time. (App Store⁠)

My only minor issue is the camera feature for taking watch photos. The alignment can be a bit inconsistent, so it would be nice to see that polished in a future update.

I’d love to see an optional way to support the development, whether through donations or a tip feature. I’d be happy to contribute to help support its continued development.

Highly recommended to any mechanical watch enthusiast. Five stars without hesitation.

### 5/5 — Love WatchTracker

*2026-07-01*

Really great app. I use it all the time to set my watches but also to record ownership of those that have come and gone. I use the data points to as it tells you if your watch is running fast or slow and it it super easy to use all the functions too. Well done to this developer, it’s brilliant.

### 4/5 — Very good

*2026-06-18*

Great app for tracking watch accuracy. Just a shame it doesn’t sync between multiple devices. Other than that, all good!

### 5/5 — Love it!

*2026-04-24*

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!!

### 4/5 — Very accurate

*2026-04-09, version 1.2.6*

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

### 5/5 — Works great

*2026-03-13, version 1.2.3*

Intuitive interface. Much better than the other apps i tried

### 3/5 — Was a great app until the data corrupted

*2026-02-27*

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)

### 5/5 — Still the Best After All These Years

*2026-02-06*

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.

### 5/5 — 5 stars

*2026-02-01, version 1.2.6*

This is a very good and reliable watch timing app. I have been using it for years.
