About
Rotor is a watch-collection app for iPhone. Everything lives on your device — no account, no cloud, no tracking. It catalogues each watch the way a collector thinks about it, remembers what you wear, and keeps your collection entirely yours.
Catalogue every watch
Brand, model, reference, movement, size, materials, box & papers, photos, tags, links and notes.
Watch of the day
A daily suggestion — weighted toward pieces you've neglected — or pick your own.
Wear tracking
Mark what's on your wrist and see a rolling 12-month wear calendar per watch and overall.
Value & stats
Purchase price, current value and a running collection total; most- and least-worn.
Owned · Wishlist · Sold
Statuses that keep your totals honest and your wishlist and sold history tidy.
