Watch Accuracy Meter

Estimate the accuracy of mechanical watches using the phone microphone. Estimations in 60 seconds - Beats per hours - Rate (seconds/day) - Beat Error (ms) - Amplitude No external hardware required Multiple measurement screens Multiple detection algorithms Should work even if a small amount of background noise is present Beats per hour setting. Lift angle setting Saving and comparing multiple results The measured values for the same watch can very depending on: - The position of the watch. - The power reserve of the watch. This app was built for watches and may not work for clocks. The measured values are estimation and can be different from the actual ones.
