Watch Tuner Timegrapher vs Clockwork
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Watch Tuner Timegrapher
This application analyzes the performance of mechanical watches by using your device's microphone to record ticking sounds. It generates a frequency diagram and provides measurements for rate, beat error, amplitude, and beats per hour.

Watch Tuner Timegrapher is an app for testing mechanical watches — both automatic and manual winding. It displays a frequency diagram of your watch and measures the rate, beat error, amplitude, and beats per hour (BPH). The app uses your device’s built-in microphone or a headset mic to record the audible ticks of the watch. For best results, use the app in a quiet environment. Background noise can affect accuracy — complete silence works best, though the built-in noise-cancelling algorithm can filter out minor sounds. The microphone must be in contact with the watch to clearly capture the ticking sound; ideally, place it against the watch’s crown during recording.
Clockwork
This app allows you to measure the accuracy of your watches using your phone's camera. It compares an image of your watch to an atomic clock to calculate its timekeeping offset. Track accuracy over time with graphs and store detailed watch information.
- Measure accuracy using images
- Atomic clock synchronization
- Accuracy over time graphs
- Store detailed watch information
- Dark mode support
- Digital and analog atomic clock

Measure the accuracy of your watches today! Clockwork includes several useful features. You can store watch information, measure watch accuracy, and set your watch using a clock synchronized with atomic time. Check it out now! _MEASUREMENTS USING IMAGES_ Most other watch measurement apps require either third-party equipment or that you press a button at a specific time. Additional equipment is often expensive, and timing a button press is difficult to do precisely. Clockwork solves this by letting you take a picture of your watch and indicate the time shown in the image. We then synchronize the image capture time with atomic time before comparing it with the time shown on the watch to calculate an offset. Taking measurements over time provides a real-world view of your watch's accuracy. _GRAPHS_ Watch your measurements over time on a beautifully crafted graph. The graph shows how your watch's accuracy changes over time and offers several modes to help you understand its performance. _WHY MEASURE?_ Knowing the accuracy of your watch is interesting on its own, but it also has several practical uses. It can indicate when it is time for a service, and documented accuracy could increase resale value, especially for vintage watches. _STORE DETAILED INFORMATION_ In case of theft or accidents, it will always help to have your information stored in a secure place. _ATOMIC CLOCK, DARK MODE AND MUCH MORE!_ Clockwork includes an atomic clock in both digital and analog formats to help you set your watch as precisely as possible. Powerful settings such as Dark or Light mode, separate day and date formats, and different ways to sort your watches let you customize the app to your liking. // Appfred AS © 2026

Verdict
The clearest difference is price: Clockwork at Free against Watch Tuner Timegrapher's $1.99. Clockwork also leads on rating (4.4 vs 3.8) and update cadence (every 3 weeks vs every 4 months). Watch Tuner Timegrapher's advantage is in-app purchases (none vs 1) and review sentiment (68% vs 45%). On ads and iOS requirement there is nothing between them.
