Only for iPhone

Free · In‑App Purchases

iPhone

Photograph your watches, keep papers and service history together, and follow your collection’s story. No Calryn account. No analytics. Optional iCloud sync. Calryn is a private catalogue for your watch collection. Keep photographs, specifications, provenance, papers and service history together, and follow your collection over time. SHOWCASE Choose which watches appear in Showcase, with edge-to-edge photography and quiet details beneath. Swipe through your collection, or let each watch’s photos advance automatically. ONE RECORD PER WATCH Keep each watch’s details together in one record: specifications, box and papers, warranty dates, straps, documents, and every service and wear entry. Photograph it, scan the receipt and warranty card, and keep it all in one place. THE STORY, IN CHAPTERS The Timeline arranges acquisitions, farewells, anniversaries and service moments by year. Chapter headings and milestones are based on the information you record. THE COLLECTION, AT A GLANCE A photographic grid of what you own, with the pieces you have moved on kept in an archive. Search the whole collection by brand, model, reference, retailer, movement or strap. FINANCES Compare your collection’s cost with your own estimates of its value. See gains and losses on watches you own and have sold, alongside spending by year and retailer. Review and update your valuations in one sitting, with a history of your estimates over time. Values are based on the figures you enter. Calryn does not source, verify or guarantee prices, and nothing in it is financial advice. WISHLIST The pieces you are considering, with retail and market notes and a private desirability rating. When one comes home, it becomes an owned watch without re-typing. PRIVATE BY DESIGN There is no Calryn account, no Calryn server and no analytics. Your collection lives on your iPhone and, if you choose, in your own private iCloud database. We are not given access to it. Within Calryn, serial numbers, purchase and sale amounts, service costs and documents have an additional layer of encryption, with the encryption key protected by iCloud Keychain. Every photo has its location and camera metadata removed before it is stored. Lock the whole app, or only Financial Data and Documents, with Face ID. YOUR DATA IS PORTABLE Back up the entire collection to a single file you control and restore it on a compatible iPhone. Create a PDF of a watch for a private sale without automatically including your purchase price, serial number or documents. Delete any watch, with its photos and documents, whenever you choose. SEVEN DAYS FREE. ONE-TIME PURCHASE. Try every feature free for seven days. Continue using Calryn with a one-time purchase. No subscription or automatic charge. If you choose not to purchase, your collection remains on your iPhone and you can still export a copy.
