About

Turn your iPhone into an acoustic timegrapher. Catalog every pocket watch with the depth a serious collector deserves — by sound, by sight, by data.

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.
