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.

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.
