WindUp is the all-in-one app for mechanical watch lovers: precision tools to set and regulate your watch, a hands-on museum that teaches you how it works, and a beautiful vault for your collection. Set it. Learn it. Collect it. THE TOOLS • Set Assistant — set your watch against atomic time, to the second, and track how many seconds a day it really drifts • Beat Rate — hold your watch to the microphone and hear its beat, or compare two movements ear to ear • Chronograph — laps, splits, flyback, and the tachymeter explained with your own runs • Power Reserve — wind it on screen, track it per watch, know before it stops • Service — every service interval tracked, so nothing is ever overdue • Fitting Room — chalk-fit any case size to your own wrist before you buy THE MUSEUM Eighteen interactive rooms you walk into and touch — scrub a single beat of the escapement frame by frame, wind a mainspring in the engine room, seat all seventeen jewels of a movement, dive to the Mariana Trench to find your watch's depth limit, and more. Every complication, hands on. THE COLLECTION • An acquisition timeline of every piece you own, with photos, specs, and values • A ranked wishlist — promote a watch to the collection the day it arrives • Paste a product link and the form fills itself; one-tap photo background removal • Dashboard: your pieces, brands, what you paid, what it's worth today • Share it: publish your collection at windup.web.app with full control over what shows WIDGETS Home Screen and Lock Screen widgets: an analog dial dressed to match your own watch, moon phase, power reserve, next service, and your collection at a glance. The tools and the museum run entirely on your device — no account, no tracking. The collection takes an optional free sign-in with Apple or Google. For people who wind their watch and mean it.
