MEASURE YOUR MECHANICAL WATCH
This app is a full-featured audio timegrapher that measures your watch’s rate, beat error, amplitude using only your iPhone’s built-in microphone.
No external sensors, clips or accessories required. Just place your phone near the watch crystal and start timing.
PROFESSIONAL-GRADE METRICS
- Rate (seconds per day gain/loss)
- Beat error (balance symmetry)
- Amplitude (balance wheel swing)
All measurements are powered by a high-accuracy audio analysis engine designed specifically for mechanical watch ticks.
