Watch Tuner Timegrapher vs Timegrapher - watch accuracy Usage & Stats

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. If you don’t need the frequency diagram, check out the Watch Tuner app. If you only want to measure rate accuracy, try Watch Tuner Lite. If you have any questions, suggestions, or issues using the app, feel free to contact me anytime.
