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 of your watch and let AI detect the brand, model, and reference number automatically.
• AI-Generated Portraits — Your watch photos are transformed into stylised, magazine-quality cards for your collection.
• Collection Management — Browse your watches in a stunning gallery with grid, full, and list layouts. Favourite, archive, and organise effortlessly.
• Measurement History — Detailed charts and trends for every watch. Track how precision changes across days, weeks, and months.
• Health Badges — See at a glance whether each watch is running within spec or needs attention.
• Wearing Habits — A calendar heatmap shows which watches you wear and when. Track streaks, rotation stats, and wrist time per watch.
• Offline First — All data is stored locally on your device. Cloud sync keeps your collection safe and accessible 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.
