Some apps log where you went. Coffer remembers what you brought back. For every trip, pack a digital trunk and fill it with the small things that made it real: the boarding pass you saved, the postcard you mailed home, the magnet from the bakery on the corner, the strange snack you couldn't translate the wrapper of. Each souvenir becomes a "keepsake", catalogued with a photo, a location, a price, a date, a note. Each trip becomes a coffer of memory. • Boarding passes and train tickets get their own ticket-stub card, with from / to, departure time, code and seat. • Scan a paper ticket with your camera and Coffer fills in the fields for you. It uses Apple's on-device VisionKit, so the image never leaves your phone. • One trip, several countries: each keepsake remembers where it came from, the trunk groups them by country, and your passport stamps each one. • An Atlas that shades in every country you've been to and pins every city, so the map fills up as you travel. • A Passport tab tracks the countries you've stamped and the achievements you've earned. • A Fridge for your favourites: hang magnets, postcards, tickets and photos on a real-looking fridge, arrange them by hand, write a note on the back, and earn new paints as your collection grows. • A leather-journal look, not another generic photo grid. • A Year in Review card for the curious: countries visited, rarest find, total spend, all from what you've already logged. • Cataloguing a collection you've built over years? Date a keepsake by month, or just the year, when that's all you remember. • One gentle reminder after each trip, to pack what you brought home. Free to start: pack your first five keepsakes into as many trunks as you like, with your Atlas, Passport and sync across your devices. Coffer Plus is a one-time unlock, no subscription. It adds unlimited keepsakes, camera ticket scanning, your Year in Review, and exporting your collection as a file. Special fridge designs (an oak icebox, a 1930s Monitor Top and more) are an optional one-time extra. Coffer is yours alone. • Your trips and photos live on your iPhone. No login required. • No ads. No data brokers. No cross-app tracking. • Anonymous usage stats help improve the app: behaviour and rough location only, never your content, names, photos or GPS position. You can switch them off in Settings. • Sign in with Apple is optional, kept in Keychain, and never sent off the device. • iCloud sync keeps your trips, keepsakes and photos on all your devices, through your own private CloudKit, never our servers. Built quietly, for people who keep their boarding passes in a shoebox under the bed.

Verdict
