Now a complete watch companion: 14 interactive tools, My Collection with a shareable profile, and widgets. WindUp is the complete companion for your mechanical watch — a dashboard of interactive tools that teach you how your watch works, and a collection that keeps every piece you own in your pocket. THE TOOLS A dashboard of live tiles — a reference clock accurate to the second, a sweeping analog dial, and fourteen full-screen showcases you can touch, turn and scrub: • Set Assistant — a countdown to push the crown at the exact second, against reference time accurate to the tick • Moon Phase — a real, rendered moon under real light; scrub through the whole lunar cycle • World Time / GMT — a 24-hour hand and a rotating bezel; turn it to read a second time zone • Chronograph — pushers, laps, a tachymetre scale, and the column wheel explained • Day · Date — the disc, the jump at midnight, and the five mornings a year the date lies • Beat Rate — hear a movement tick at 18,000, 21,600, 28,800 or 36,000 beats per hour, and listen to your own • Sun — sunrise and sunset computed on your device, with the watches that show them • Equation of Time — how far a sundial runs from your watch today, and why • Movement — an annotated calibre, part by part, from mainspring to balance • Escapement — a Swiss lever escapement beating in slow motion • Power Reserve — the mainspring gauge, and a winding log for each of your watches • Service — service history and reminders, tracked per watch • Water Resistance — an interactive descent from the surface to the floor of the Mariana Trench, with a line at exactly where your watch taps out • Glossary — the vocabulary of horology, illustrated Every tool explains the complication behind it: what the mechanism is, how it moves, why watchmakers built it that way. MY COLLECTION Your watch case in your pocket: • An acquisition timeline of every piece you own, with photos, specs and values • A ranked wishlist for the ones still out there — promote a watch to the collection the day it arrives • Paste a product link and the form fills itself • Photos with crop and one-tap background removal • A collection dashboard: pieces, brands, what you paid, what it's worth today • Power reserve and service tracked per watch SHARE IT Publish your collection at a link — a profile page with your timeline, wishlist and stats. You decide exactly what the page shows: hide prices, hide values, hide the wishlist, or keep the whole thing private. Share a card of your collection with friends. WIDGETS Home Screen and Lock Screen widgets: an analog dial you can dress to match your own watch, the moon, your power reserve, your next service, and your collection at a glance. The watch tools run entirely on your device — no account, no tracking. My Collection is optional and takes a free sign-in with Apple or Google, so your collection can follow you across devices. For people who wind their watch and mean it.
