Watch Tuner 1.12

Watch Tuner is an application for testing mechanical and automatic watches, specially designed to measure important parameters such as rate, beat error, amplitude, and beats per hour. This app utilizes the built-in or headset microphone of your device to record the audible ticks of the watch.

With Watch Tuner, you can now assess the quality and stability of rate accuracy, amplitude, and beat error in mechanical watch movements using your iPhone. Additionally, you have access to a history of results to track any changes over time.

For optimal results, it is recommended to conduct measurements in a quiet environment as ambient noises may impact result accuracy. It is advised to aim for complete silence for the most precise readings.

To ensure accurate recordings, the suggested method is to place the headset microphone near the crown of the watch. For best outcomes, it is recommended to use the original Apple EarPods.

If your needs are more basic and you only require rate accuracy checks, you may find Watch Tuner Lite to be a suitable alternative to the full Watch Tuner application. For those seeking a frequency diagram, Watch Tuner Timegrapher stands out as the most advanced app in the Watch Tuner series.
