Collectors tend to keep their watches' details in a spreadsheet, the photos in an album, the service receipts in a drawer and their accuracy readings nowhere at all. Horology brings them together, with tools that show how each watch is really doing.

What Horology does
- Keeps a watch collection with references, serial numbers, papers, purchase details, photos and a dial drawn for every watch.
- Logs the watch you wear each day, and shows your rotation score, cost per wear and wear patterns.
- Measures accuracy with Time Check and a timegrapher that uses your iPhone's microphone.
- Reminds you when a watch is due for service, and exports an insurance report.
Who it's for
Collectors with a few watches or a few dozen, enthusiasts who want to know how their mechanical watches are running, and anyone who wants their collection's details ready for a sale or an insurer.
Privacy
Horology has no account and no ads, and doesn't track you. Usage statistics and crash reports help improve the app; they never carry collection data, and you can turn them off in Settings. Read the privacy policy.
