WORN is a companion and wear tracker for a watch collection: the pieces you own, the days you wear them, and the ones you are still deciding about. Made for iPhone Duo. Open it and WORN spreads across both pages; closed, a side rail keeps everything in reach. HOUSES Each great watch house as a magazine issue, starting with Rolex. The story of the house is told in chapters you play, each with a short film and the watch to turn in 3D. The first chapter of every house is free. WORN is independent and not affiliated with any watch brand. THE GRAND TOUR OF TIME Travel through the history of timekeeping, from a baboon bone with 29 notches to the quartz second: 109 hand-drawn stops, each a short chapter with the real story behind it. Eleven are free to play, a chapter of the day opens with your wrist check, and the Grand Tour Pass opens every stop for good. WORN Premium includes every stop. MOVEMENT LAB Eleven short films on how a mechanical watch works, one part at a time. Like them and comment. THE COLLECTION Every watch sits on its own cushion in a box you arrange yourself. Behind each piece: photos, box and papers, purchase price, service history, and the movement inside it. Cost per wear divides what you paid by the days you actually wore it, and it usually argues for wearing more, not buying more. THE DIARY A calendar of every wear, written by tapping the watch you put on. Journal entries, a streak drawn as a mainspring you keep wound, and charts of rotation, brands and value. THE WALL AND LETTERS Post a wrist shot to the week's Wall, sort and filter it by movement and brand, and win a seal on Sunday. Write to a collector from their print: letters arrive sealed in wax, and the reader chooses to accept or decline. LISTENING Rest your iPhone against the caseback of a mechanical watch and WORN listens to the beat like a timegrapher. Drift is reported in seconds a day and kept as an accuracy log per watch, so you see a service coming. DISCOVER Decks of the watches you want, your Grails and your next buy, in your own order. Search all 46,000 watches in the catalogue by fit and size. Narrow the search to one or more brands. If a watch is missing, ask for it to be added; if it has no picture, send one. A watch's page shows how it fits your wrist, its price and its cost per wear for you, and what you have saved toward it. TRY IT ON FIRST One photo of your wrist, scaled by your wrist measurement, so a 36 mm dress watch and a 44 mm diver land differently on the same arm. An optional AI render arrives as an instant print; Credits are charged only when a picture comes back. AI, ONLY WHEN YOU ASK Point the camera at a watch and WORN identifies it. Photograph today's outfit and the Mirror picks the watch to wear with it. No photo leaves your device in the background: every AI feature is a deliberate tap, covered by a consent you can withdraw in Settings. WHAT IT COSTS The collection box, the diary and listening are free, and every watch you add has a Slot. AI actions cost Credits, bought in packs (30, 120 or 350) that never expire; a new install starts with 20. A house chapter costs 10 or 15 Credits. WORN Premium is optional: 75 Credits every month that roll over, every Grand Tour stop, and half price on house chapters. The Grand Tour Pass is a one-time purchase that opens every stop, plays every house game and halves house chapter prices. A whole house costs 30% less than its chapters. PRIVACY, PLAINLY Your watches, wear diary and recordings live on your device and in your own private iCloud database, which we cannot read. The privacy policy names every service the app talks to and exactly what each one receives.
