WearKeeper keeps your watch collection, and the story of how you wear it, on your own PC. Add each watch with photos, reference, purchase details and notes. Log a wear with one click and WearKeeper keeps a real history of what you reach for — and shows cost per wear falling the more you wear each piece. A watch bought for $2,000 and worn 200 times has cost $10 a wear. Your collection lives on your computer. There is no WearKeeper account and no cloud service: nothing is uploaded to us. YOUR COLLECTION AT A GLANCE Every watch, its photos, last-worn date, wear count and cost per wear on one screen. Search, sort and filter as the collection grows, and let the rotation pick suggest a watch that has gone quiet. KNOW WHAT YOU WEAR Wear history, a year-at-a-glance heatmap, streaks and collection-wide statistics show which pieces earn their place in the box. OWNERSHIP RECORDS Keep service history and the next service date, box-and-papers status, receipts and notes together with each watch. Export a clean PDF of the collection for your records or insurance. A WEARING DIARY Write about the occasions — the trip, the wedding, the ordinary Tuesday — with a photo, and look back on them by watch or by month. ADD WATCHES QUICKLY Paste a listing link and WearKeeper fills in the brand, model, price and photo it can find, or import a spreadsheet of your whole collection as CSV. MOVE BETWEEN DEVICES WITHOUT A SERVER A WearKeeper backup is a single file. Make one on Android and restore it on Windows, or the other way round — photos included. Password-protected backups are available. SMART SUGGESTIONS FROM YOUR OWN DATA Ask what to wear today, or what your collection is missing. WearKeeper works it out from your own watches and wear history — every date, day count, price and ranking is calculated by the app itself, on your PC, in every language it supports. OPTIONAL ON-DEVICE AI An optional AI model that runs on your PC (a one-time download of about 380 MB) helps with writing: it polishes a diary entry in the language you wrote it — you see the result first and choose whether to keep it — and helps read the details from a pasted listing link. In English it can also put WearKeeper's suggestions into its own words, only when they match the facts. Nothing you write is sent to us, and WearKeeper works fully without it. WearKeeper is not a valuation tool and does not estimate resale value or give financial advice. One purchase. No ads, no subscription, no account.
