Every watch you own has been somewhere with you. Caliber keeps them together in one private case, with their photos, their papers, and every day you wore them. Most watch apps want to know what your watches are worth. Caliber is about wearing them. One tap logs the watch on your wrist. There are no valuations, no marketplace, and no account. We never see your collection. THE CASE Your favorite shot of each watch becomes its cover, whether it is on the wrist or a close-up of the dial. You can crop it right in the app. A watch without a photo still appears, drawn from its specifications. THE RECORD Each watch has a Collection Record, a single page that shows its crystal, dial, movement, and case with everything you know about it. You can share it as an image. It does not certify authenticity. THE PAPERS You can scan warranty cards and receipts with your camera. Caliber keeps them with the watch they belong to. THE JOURNAL You can log a wear from the app or from a Home Screen widget. Your wears fill in a calendar and a map of the places you went. Location stays off unless you turn it on, and you choose how much Caliber records. THE NUMBERS Caliber shows your rotation, your weekday and weekend favorites, the case sizes you wear most, and the watches that can share a strap. Every number comes from your own records. Nothing is estimated. TWO APPEARANCES Dark is obsidian and gold. Light is alabaster and bronze. Caliber can also follow your device, and the widget matches whichever you choose. A CATALOG THAT GROWS Caliber fills in the case, diameter, dial, movement, and caliber from a reference number. If the catalog does not know a watch yet, Caliber saves it exactly as you entered it. If a later update adds that reference, Caliber fills in only the fields you left blank. YOURS TO KEEP If you keep your watches in a spreadsheet, Caliber can bring them in. You can also take everything out at any time, including photos, documents, and every logged wear, in one archive that opens without Caliber. Export is always free. ICLOUD SYNC With a Reserve membership, your collection is the same on every iPhone and iPad signed in to your Apple Account. It also appears on your new devices automatically. Caliber keeps it up to date through your own iCloud, which we cannot read. OUR WORD Caliber earns money only from memberships. It shows no ads, now or later, and we never sell your data. We put these promises in writing so you can hold us to them. CALIBER RESERVE The free case holds three watches. Reserve removes the limit. It adds Follow the Day. If you turn it on, Caliber saves where each watch has been throughout the day. It also adds iCloud sync and the deeper numbers. Monthly, $9.99 a month. Renews each month until you cancel. Annual, $79.99 a year. The first two weeks are complimentary. Lifetime, $279.99 once. Yours for good. Whatever you choose, everything in your case stays yours. You never need a membership to view your watches, log wears, or export. Caliber is an independent app and is not affiliated with or endorsed by any watch brand. All brand names and trademarks belong to their respective owners.
