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. See current subscription pricing in the app.

I was just beginning to enjoy the premium features of the app … but version 1.5.2 caused several issues. I got an email reply and updated… all those issues seem to be resolved and it’s working. Thanks for your help resolving this for paying customers.

Update On My Last Review

The developer responded to my email, my concerns, fixed all of the bugs and the app is back to working very well. I revise my last review and would delete it if I could.
Developer Response
Thanks a lot! Hope you enjoy the app. Please drop me an email anytime if you have any suggestions, feedback or just chat 🙂.
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.
