Timegrapher app: check your watch rate in seconds per day with the phone mic
A timegrapher app for mechanical watches: listen to the ticks with your phone mic and see the rate in seconds per day. Hold your watch near the phone in a quiet room. Watch Timegrapher listens to the tick and estimates how fast or slow it runs, plus its beat rate (BPH). Features - 60 second rate check in seconds per day - Beat rate (BPH) estimate - Basic session card to share - Recent sessions kept on your phone - Sound is analysed on your phone Pro A one-time Pro unlock adds a beat error graph, multi-position checks, lift angle presets and clean picture cards. Good to know Use a quiet room. A contact mic can help. It gives a practical estimate, not the precision of a bench timegrapher. Pricing Free: 60 second rate and BPH with a watermarked card. Watch Timegrapher Pro is a one-time lifetime unlock. No subscription.
