App Description
Oscillo is a watch timegrapher for iPhone. Measure rate, beat error, and amplitude — the same metrics a professional watchmaker checks — using just your iPhone microphone. No adapters, no cables, no expensive equipment. Built for mechanical watch collectors who care about precision.
HOW TO MEASURE
1. Place the iPhone microphone flat against the watch crystal or case back.
2. Record a few seconds of tick sounds.
3. Get your rate, beat error, and amplitude instantly.
KEY FEATURES
• Watch Rate Checker — Measure rate (seconds/day), beat error (ms), and amplitude (degrees) in seconds. Works with beat rates from 12,000 to 72,000 BPH.
• AI Watch Identification — Snap a photo and let AI detect the brand, model, and reference number automatically.
• AI-Generated Portraits — Your watch photos become stylised, magazine-quality cards for your collection.
• Collection Management — Browse your watches in a beautiful gallery with grid, full, and list layouts. Favourite, archive, reorder, and organise effortlessly.
• Measurement History — Detailed charts and trends for every watch, with health badges that flag whether a watch is running within spec.
• Precision Tracking — Run multi-day measurement cycles. Capture manual readings from the dial, watch drift accumulate, and confirm whether a service or regulation actually held.
• Weekly Watch Report — A seven-day summary of your collection: average rate, most-worn watch, best reading, and suggested next actions.
• Profile and Wearing Habits — A personal calendar of activity, collection milestones, timing performance, and a heatmap that shows which watches you wear and when.
• Reminders — Optional local notifications nudge you to log wrist time, capture the next precision reading, or open your weekly report.
• Offline First — All data is stored locally on your device. Cloud sync keeps your collection safe across devices.
ACCURACY & ENVIRONMENT
• Best results in a quiet room — background noise can affect readings.
• Place the case back flat against the microphone for a strong, consistent signal.
• If readings seem unstable, move to a quieter space or adjust mic position.
