Store description excerpt

Tempochron turns your iPhone into a practical timing companion for mechanical watches. Use the iPhone microphone or a compatible external input to listen to watch ticks, estimate rate, beat error, and timing stability. Or compare elapsed time between two dial photos: align each photo with an atomic-time reference to estimate daily rate without touching the watch. Save readings by watch for service notes, regulation checks, and before/after comparisons. Features: - Live rate and beat error measurement - Camera time checks with daily-rate history - Compatible external wired or USB microphones when iOS exposes them as audio inputs - Automatic BPH detection for common mechanical movements - Watch profiles with purchase, warranty, and service history - Private iCloud sync for watch profiles, care records, and measurement history; audio recordings stay on this device - Multi-position timing sessions for dial-up, dial-down, crown-up, crown-down, crown-left, and crown-right checks - Signal scope and advanced diagnostics for evaluating recording quality - CSV, JSON, PDF, and raw audio export tools with Tempochron Pro Tempochron is designed as a field screening tool, not a certified timing machine. Results depend on microphone contact, background noise, watch position, mainspring state, and movement condition. Use proper bench equipment for final regulation decisions.
