## What is Horology?

Measure your watches' accuracy with your iPhone, log what you wear and keep your whole collection in one place. Free for up to three watches.

YOUR COLLECTION
• Add a watch in seconds from a built-in catalogue of more than 36,000 references, or paste a listing from a dealer's website: Horology reads it (with Apple Intelligence on devices that have it) and suggests the matching reference.
• Brands include Rolex, Omega, Tudor, Patek Philippe, Audemars Piguet, Cartier, TAG Heuer, Breitling, IWC, Panerai, Seiko, Grand Seiko, Longines, Tissot, Hamilton, Oris, Citizen, Casio, among more than 120.
• Every watch gets a dial drawn in its own colours, or studio photos with the background removed on your iPhone.
• Keep references, serial numbers, papers, prices and service history together, with a wishlist and a record of the watches you've sold.

WHAT YOU REALLY WEAR
• Log today's watch with one tap: in the app, from a widget, with Siri, from Control Center or on your Apple Watch.
• See your rotation score, cost per wear, collection value and wear patterns month by month.

ACCURACY
• Timegrapher: hold your iPhone against the watch to measure rate, beat error and amplitude in 30 seconds, in one position or all six.
• Time Check: compare your watch with atomic time today and again tomorrow for its real daily rate.
• Follow each watch's accuracy over time.

SERVICE
• Movement-aware reminders tell you when a watch is due for service.
• Export an insurance report as a PDF, or your collection as a spreadsheet.

PRIVATE BY DESIGN
No account and no ads. Your collection stays on your devices and syncs through your own iCloud. Listings are read and microphone sound is analysed on your iPhone; sound is never recorded.

HOROLOGY PRO
The free version holds up to three watches. Horology Pro adds unlimited watches, the timegrapher and 6-position testing, Insights, accuracy history, service reminders, the insurance report and studio photos. Choose a monthly or yearly subscription (the yearly plan starts with a free week) or a one-time lifetime purchase.

Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple Account, and you can manage or cancel subscriptions in your account settings.
