Oscillo vs Timegrapher Advanced

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. Payments and Renewal Oscillo offers limited free use and optional Pro purchases, including subscriptions and a one-time purchase. Payment will be charged to your Apple Account at confirmation of purchase. Subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period.

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.
