About Pocket Watch Box
Turn your iPhone into an acoustic timegrapher. Catalog every pocket watch with the depth a serious collector deserves — by sound, by sight, by data. Pocket Watch Box is a private collection manager designed for enthusiasts of mechanical pocket watches, antique stopwatches, and vintage chronographs. Every detail — from the antique typography to the on-device acoustic timegrapher — exists because a real collector wanted it. — FEATURES — CATALOG • Up to 10 photos per timepiece, with subject-aware background cleanup • Detailed specs: caliber, BPH, escapement, jewels, complications, case • Purchase records, provenance, accessories • Operating videos to capture each watch in motion ACOUSTIC TIMEGRAPHER (Curator) • Detect BPH, daily rate, beat error, and stability from your iPhone mic • Live oscilloscope-style waveform visualization • Autocorrelation-based detection for mechanical accuracy • No external $5,000 machine required LONG-TERM RATE TRACKING (Curator) • Manual drift logs and acoustic readings on a single trend chart • Catch slow degradation before your watch needs service SERVICE & OH REMINDERS • Track every overhaul, service, and component change • Configurable reminders 30 days before each watch is due ICLOUD SYNC (Curator) • Quietly synced across all your Apple devices • Stored only in your private iCloud — the developer cannot see it COLLECTION INSIGHTS (Curator) • Total value across multiple currencies • Maker, era, condition, and operating-status breakdowns • CSV export for permanent archival — CURATOR PLAN — Pocket Watch Box is free for up to 10 timepieces with banner ads. Become a Curator to unlock unlimited timepieces, every diagnostic tool, iCloud sync, collection statistics, exports, and an ad-free experience. • Curator · Monthly (auto-renewable subscription) • Curator · Yearly (auto-renewable subscription, best value) Subscriptions automatically renew unless turned off at least 24 hours before the end of the current period. Manage and cancel from your Apple ID settings. — PRIVACY-FIRST — No accounts. No servers. No tracking. Your collection lives on your device — and, optionally, in your private iCloud. Audio analyzed by the Acoustic Timegrapher is processed entirely on-device and is never recorded or transmitted. — CRAFTED BY A COLLECTOR — Built by a pocket watch collector who couldn't find a tool that respected the craft. Every detail exists because a real collector wanted it. Terms: https://lineocean.com/pocketwatchbox/ Privacy: https://lineocean.com/pocketwatchbox/
What’s new
Version 1.0.2 · Updated July 24, 2026
WIND & WEAR — your collection now has a daily rhythm • Today's Wind: a daily pick of which watch to wind and carry, chosen by how long each piece has rested (favorites come around a little more often). Logging the wind takes one tap. • Optional morning notification tells you whose day it is — by name. SERIAL → YEAR LOOKUP • Type a movement serial for Waltham, Elgin, Hamilton, Illinois, or South Bend, and the app suggests the production year from classic factory-ledger data. Fully offline. • Successful matches appear on the watch's page — "The era of 1908." SERVICE & RATE • New sort: "OH due, soonest" — see which watches need attention first. • Service cost totals in Data & Analysis, including the past 12 months. • Rate trend charts now mark each overhaul with a vertical line, so post-service improvement is visible at a glance. ALSO IN THIS UPDATE • Try the acoustic timegrapher once, free. • Much smoother scrolling for photo-heavy collections. • Winding dates included in CSV export, plus reminder reliability fixes.
