Watch Timegrapher: Rate Mic

A timegrapher app for mechanical watches. Rest your watch on the phone and Watch Timegrapher listens to the ticks through the mic, then shows how many seconds a day it gains or loses. How it works Every tick is timed and matched to its beat, so a missed tick or a stray click does not throw the reading off. The rate gets steadier the longer you listen, and a plus or minus band shows how tight it is. The trace draws each beat as a dot, like a bench timegrapher: a slope means the watch runs fast or slow, and two lines mean beat error. Free - 60 second rate check in seconds per day - Beat rate found for you, from 14,400 to 43,200 BPH, or pick it yourself - Live timegrapher trace - Reading cards to save and share - Recent readings kept on your phone Pro, a one-time unlock - Beat error on every reading - Listen as long as you like, past 60 seconds - Guided six position test with the average and the spread - Watch log with rate history for each of your watches - Calibration for your phone - Clean cards without the footer line, plus skins Good to know Use a quiet room and rest the watch on the phone near the mic. A contact mic can help. Readings are estimates from your phone mic, and a bench timegrapher is more accurate. Sound is analysed on your phone and nothing is uploaded. Pricing Free to download. Watch Timegrapher Pro is a one-time lifetime unlock. No subscription.
