Twixt Time vs Watch Tuner
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Twixt Time
This app helps you track the long-term accuracy of your watches and clocks. By taking precisely timed photos of your timepiece's dial, it analyzes the time displayed against internet-accurate servers to calculate its rate and cumulative gain or loss.
- Track watch and clock accuracy
- Precisely timed dial snapshots
- Analyze rate and cumulative gain/loss
- Supports various dial configurations
- Automatic timezone monitoring
- Works with GMT and chronograph watches

Twixt Time helps track the longterm accuracy of watches and clocks, by collecting & analyzing precisely timed snapshots of their dials. Use Twixt Time to take a picture of the dial of an analog clock or watch. Each picture captures the exact time displayed on the dial. Twixt also notes the precise instant that the each snapshot was taken, by communicating with highly accurate NTP timeservers on the Internet. A new snapshot of each timepiece can be added everyday. Using the information from 2 or more snapshots of the same timepiece, Twixt will calculate and show you how precisely the watch or clock is keeping time. Twixt tracks the most recent rate, overall average rate, and cumulative gain or loss for each timepiece. Supported dial configurations: * Hour & minute hands with a central seconds hand * Hour & minute hands with seconds displayed in a subdial * Hour & minute hands only Does Twixt Time work with GMT watches? Yes. Twixt Time does not need to track the 24 hour hand of GMT watches to measure their precision. It is only necessary to track the hour, minute, and second hands. For GMT watches with central seconds, select the "central seconds" layout. For GMT watches with an offset or subdial seconds hand, select the "subdial seconds" layout. Twixt Time automatically monitors timezone changes based on the timezone setting of the iPhone or iPod touch. Does Twixt Time work with chronograph watches? Yes. The chronograph functions of a watch do not need to be measured to track the precision of the watch. Twixt Time tracks the precision of chronographs, as well as watches with other complications, in the exact same way that it tracks the precision of a normal, time-only watch. If the central seconds hand can be stopped and reset with the chronograph function, select the "subdial seconds" layout to track the small seconds hand with Twixt Time. If the central seconds hand continues to move when the chronograph is stopped, but the small seconds hand stops, select the "central seconds" layout to track the central seconds hand with Twixt Time. Most chronographs will use a subdial seconds layout. Does Twixt Time work with watches that have an offset seconds hand? Yes. For watches with a second hand that is not concentric with the hour and minute hands, select the "subdial seconds" layout. Does Twixt Time work with quartz watches and clocks? Or other watches and clocks that are powered by batteries? Yes. Twixt Time works with battery powered watches and clocks that display the time with an hour, minute, and/or second hand. It does not work with watches or clocks that only display the time digitally. ---------- Twixt Time is not affiliated with or endorsed by any watch or clock brand. The timepieces shown are for demonstration purposes only.
Watch Tuner
This application tests mechanical and automatic watches by measuring rate, beat error, and amplitude using your device's microphone. It provides a history of results for tracking watch quality and stability. For best accuracy, use in a quiet environment.
- Measures rate, beat error, and amplitude
- Uses device microphone for recording ticks
- Provides results history
- Supports iPhone and iPod
- Quiet environment recommended for accuracy

Watch Tuner is a mechanical and automatic watch testing application designed to measure following parameters: - rate - beat error - amplitude - beats per hour The application uses the build-in or headset microphone to record audible ticks of the watch. You can measure now with your iPhone the quality and stability of the rate accuracy, amplitude and beat error of mechanical watch movements. You can also take advantage of results history. Use in a quiet environment. Any ambient noises can affect result accuracy. Complete silence is the best. Recommended way to record the ticks is to touch the crown of the watch with the headset microphone. You will get the best results using original Apple EarPods. If you don't need such advanced tool as Watch Tuner and all you need is to the check rate accuracy, maybe it's worth to try Watch Tuner Lite - a little brother of Watch Tuner application. If you need frequency diagram look at Watch Tuner Timegrapher - the most sophisticated app of Watch Tuner series.
