Oscillo is a watch timegrapher for iPhone. Use your iPhone microphone to measure the same metrics a professional watchmaker checks: rate, beat error, and amplitude. No adapters, cables, or 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. Start recording the tick sounds and wait for the measurement to finish. 3. Review your rate, beat error, and amplitude. KEY FEATURES • Watch Rate Checker — Measure rate (seconds/day), beat error (ms), and amplitude (degrees). Supports the beat rates listed below. • AI Watch Identification — Snap a photo and let AI detect the brand, model, and reference number automatically. • AI-Generated Portraits — Oscillo turns your watch photos into magazine-style cards for your collection. • Collection Management — Browse your watches in grid, full, or list views. Mark watches as favorites, archive them, change their order, and organize your collection. • Measurement History — Detailed charts and trends for every watch, with health badges that help you interpret your measurements. • Precision Tracking — Record manual readings from the dial and follow your watch’s drift over days. Compare observations before and after a regulation or service. • Guided Measurement Cycles — Record timegrapher readings in different watch positions. With Oscillo Pro, complete all six positions and compare results with a saved reference cycle. • 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 remind you to log which watch you wore, capture the next precision reading, or open your weekly report. • Offline Access — Your saved collection and measurements are available on your device. Cloud sync and AI features require an internet connection. 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. • Supported beat rates: 12,000 / 14,400 / 17,280 / 18,000 / 19,800 / 21,600 / 25,200 / 28,800 / 36,000 / 43,200 / 72,000 BPH. DESIGNED FOR COLLECTORS Whether you own one watch or fifty, Oscillo helps you follow changes in each movement’s timing performance over time.

Verdict
