User reviews

Very close to ideal

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.

A Hidden Gem for Watch Enthusiasts ⭐⭐⭐⭐⭐

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.

Love WatchTracker

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.

Very good

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

Love it!

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!!

FAQ

What does Watch Tracker do?

Watch Tracker is an application designed to precisely measure and track the accuracy of your wristwatch. It compares your watch's time to an atomic clock, recording any gains or losses to help you understand its performance over time.

How does Watch Tracker measure accuracy?

The app utilizes best-fit analysis to calculate how many seconds your watch gains or loses per day. You simply tap a button when your watch's time matches the app's displayed time, and the app handles the rest of the measurement and synchronization.

Can I track multiple watches with this app?

Yes, Watch Tracker allows you to track multiple watches simultaneously. This feature is useful for collectors or individuals who own several timepieces and want to monitor each one's accuracy independently.

What kind of data does the app provide?

The app provides detailed graphs of your recorded data points, showing rates and variance in your watch's timekeeping. It also saves this data in CSV files, which can be easily opened and analyzed with any spreadsheet software.

Is Watch Tracker free to use?

Based on the provided information, Watch Tracker is a paid application. It does not appear to have in-app purchases or advertisements, suggesting a one-time purchase for full functionality.
