Rotor – Watch Collection

Catalogue your watches, track what you wear, and keep it all private on your device. A calm, offline home for your collection.

Rotor is a calm, private home for your watch collection. Everything lives on your device — no account, no cloud, no tracking.

Catalogue every watch the way a collector thinks about it: brand, model, reference, movement, diameter, lug-to-lug, thickness, case material, water resistance, year, and box & papers. Add multiple photos, tags, external links and notes.

Wear it and remember it. Mark what's on your wrist each day, and see a rolling 12-month wear calendar for every watch and for the whole collection. A "Watch of the Day" suggests something to wear — weighted toward pieces you've neglected — or pick your own.

Know your collection. Track purchase price and current value with a running collection total, see which watches you wear most and least, and how many days you've logged.

Organise with intent. Give each watch a status — owned, wishlist or sold — so your value totals reflect only what you actually own, while your wishlist and sold history stay out of the way. Search, filter by tag, and sort by size, year, value or wear.

Show it off. Turn any watch into a polished Instagram-story image right in the app — pick the photo, edit the caption, choose a layout — then save it to your photos or share it. All rendered on your device.

Yours to keep. Export your entire collection — data and photos — as a single backup file you control, and restore it on a new phone in seconds. Available in English and German, following your device language or your choice.

No sign-up. No subscription. No internet required.
