Zen Horology: Watch Collection

Timegrapher & Accuracy Tracker

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Keep your watch collection, wear history and service records together. Zen Horology helps watch collectors organize their watches, follow accuracy over time and explore phone-based timegrapher measurements. YOUR COLLECTION, ORGANIZED Save photos, brand, model, reference, serial number, movement and case details. Keep purchase information, documents, warranty cards and the story behind each watch. Search and sort your collection when it grows. TRACK WATCH ACCURACY Set a reference, log checkpoints and follow daily rate in seconds per day. Review drift over time instead of judging a watch from one reading. Use the reference clock and Sync Assistant to help set a watch. A TIMEGRAPHER ON YOUR PHONE Use your iPhone microphone to explore beat rate and a live trace from a mechanical watch. Record readings in different positions. Premium adds advanced metrics including beat error and approximate amplitude. Phone measurements depend on the device, surroundings, placement and watch. Treat them as estimates for personal tracking, not a professional diagnosis or a replacement for a watchmaker. The magnetism check is a screening tool, not proof that a watch needs service. KNOW WHAT YOU WEAR Log wrist time and see your rotation over the last week or month. Review collection insights and keep service dates, repairs and documents with the relevant watch. VALUE AND OWNERSHIP Record purchase prices in different currencies and view a converted collection total. These are your recorded values, not a professional appraisal or an insurance valuation. YOUR RECORDS, YOUR BACKUP Your collection database stays on your device. Photos and documents use your personal iCloud Drive automatically when it is available, with local storage as a fallback. Creating and restoring backups requires iCloud Drive; automatic backup has a separate setting. Usage analytics and diagnostics are described in our privacy policy. No account is required and there are no ads. Create a Watch Shot card when you want to share a watch. START WITH TWO WATCHES The free plan includes two watches, accuracy and wear tracking, reference time, magnetism screening, timegrapher beat rate, documents and backup. Premium unlocks unlimited watches and advanced timegrapher metrics.

Zen Horology now opens in about half the time and scrolls smoothly from the first second. Your watch photos are now kept on your phone, so the vault shows every photo even with no internet connection. The Zen Whisperer insight now appears twice a week instead of every day, so each one is worth reading. The Sync clock also stops running when you are not looking at it, which saves battery.
