Anglage: Watch Timegrapher

Anglage turns your phone into a watch timegrapher. Hold a mechanical watch against the phone, near the microphone, and its ticking becomes a live paperstrip trace with the three numbers that matter: rate (seconds per day), beat error, and balance amplitude. MEASURE LIKE AN INSTRUMENT • Live paperstrip: committed ink never redraws; you watch the watch, not a guess. A live microphone band shows exactly what the app hears. • Rate from a regression over every tick, not a rough average, with an honest ± precision figure on every reading. If we're not sure, you see it. • Signed beat error and lift-angle-correct amplitude. • Beat-rate auto-detection from 12,000 to 72,000 bph, high-beat included. SIX POSITIONS, LIKE A BENCH A guided run walks the watch through dial up, dial down, and all four crown positions, then reports per-position rates and your positional delta, the number regulators actually chase. IS IT MAGNETIZED? A magnetized watch runs fast, and regulating it will not fix it. The magnetism check reads your phone's compass sensor: hold the watch against the phone, once each way up, and Anglage shows the field on each side and whether it changed direction when you flipped the watch. That tells a magnetized movement apart from plain steel, so you know when to have it demagnetized first. A COLLECTION THAT REMEMBERS Every session is saved to a watch with its position, amplitude and notes. Rate history charts, caliber autofill for common movements, and cloud backup of your data (never your audio). PRIVATE BY DESIGN Audio is analyzed on your device in real time and never recorded, stored, or uploaded. Anywhere. Anglage is free, supported by unobtrusive ads that never appear during a measurement. A note on honesty: a phone microphone is not a contact sensor. Anglage shows its confidence on every reading instead of pretending lab precision. For certification-grade numbers you still want a bench machine. For everything else, it's in your pocket.
