Original Summary

Hey r/SideProject — watch guy here. I kept wanting to check the accuracy of my mechanicals without buying a $200 timegrapher, so I built WindUp. What it does: - Uses your iPhone mic as a timegrapher — beat rate, beat error, amplitude - Accuracy tracking per watch over time — log daily rates, watch the drift - Collection manager — your watches, photos, service history - Interactive museum of iconic movements to explore Free, no ads, iOS only for now. Honest question for fellow builders: the mic-as-timegrapher is the shakiest part — phone mics vary wildly. Anyone done audio signal processing on mobile and have tips for calibrating across devices? https://apps.apple.com/us/app/windup/id6798121124 Happy to answer anything about the build — SwiftUI, AVFoundation audio pipeline, etc.   submitted by   /u/realethanbradberry [link]   [comments]
