Timegrapher Advanced turns your iPhone into a portable watch timing instrument—ideal for hobbyists, collectors, and professionals who want quick, clear readings at the bench or on the go. Place a mechanical watch on a piezo or on top of an external mic, press Start, and watch a live screen measure the rate (s/d), beat error (ms), and amplitude (°). Core measurements • Rate in seconds per day • Beat error in milliseconds • Amplitude in degrees (with adjustable lift angle) • Manual BPH for common beat rates • Sensitivity control plus an auto sensitivity sweep to find a clean pickup level Chart that works like a real timegrapher • Dual-line tick/tock paperstrip with progressive slope from rate • Line separation tracks beat error (near-overlap when BE is excellent) • Portrait dashboard or full-screen landscape chart with rate, BE, amp, BPH, and lift • Customizable colors, scale (±100 to ±999), and optional scale gridlines • Optional live tick waveform pip to confirm clean escapement sound Automatic sweep • Sensitivity sweep will scan through your microphone's sensitivity range to autodetect the optimal setting used for capturing data • Sensitivity sweep uses a weighted algorithm to measure signal, noise, captured data, events, and elects the best data on a scoring mechanism Calibration you control • Factory default tuned from real multi-watch sessions • Create and edit profiles against your hardware timegrapher (gold standard) • One-tap Calibrate after 20 seconds of live data to capture app raw and bake offsets Workflow with Timegrapher Logging (separate app) • Optional deep-link integration: measure an orientation (including isochronism / 24h rows) in Advanced, then Capture and Send straight into Logging Built for real use • Metrics clear to −/− when the watch is off the mic—no frozen last reading • Quiet-room friendly piezo/mic workflow with optional tick noise filtering • Diagram noise reduction for a calmer strip • Clean, focused UI Whether you’re regulating a custom build, checking a Rolex, or logging a full position set, Timegrapher Advanced gives you a clear chart and numbers you can trust—and align to the instrument you already use. ## Key features - Live rate, beat error, and amplitude measurements - Dual-line tick/tock paperstrip chart - Automatic sensitivity sweep for optimal settings - Adjustable lift angle and manual BPH - Customizable chart colors and scales - Calibration profiles for hardware timegraphers ## Frequently asked questions about Timegrapher Advanced ### What is Timegrapher Advanced?
