Every watch has a story. Crownlog gives yours a place to live. Keep your collection and wishlist together on your Mac, with the details you actually want to remember: references, purchase prices, service dates, favorite pieces, and the watches you're still looking for. YOUR COLLECTION, AT A GLANCE Browse a gallery or a compact list. Search by brand, model, reference, tag, or note. Keep owned watches separate from your wishlist, favorite your next purchase, and give each watch a grail score. KEEP TRACK OF THE DETAILS Record purchases, log the watches you wear, and keep an eye on upcoming service. Listing-price history helps you see what changed. Add target prices to spot watches that reach your budget. A SHORTLIST YOU CAN COMPARE Compare up to three watches side by side. If you're undecided, Watch roulette gives a wishlist watch another turn in the spotlight. PRICES WITH CONTEXT See purchase cost, tracked collection value, and possible wishlist spend in your preferred currency. ECB reference rates work offline after they're saved. Record your own market estimates, or connect a personal The Watch Info API key and confirm the matching model yourself. Provider estimates show their source, date, range, sample count, and confidence. FIND SOMETHING NEW Follow brands and retailers. Read public product details from a listing, or fetch a catalog or collection page into your Discovery tray. Review each find before adding it. Website support varies; manual entry is always available. PHOTOS YOU CAN KEEP Add your own photo or save an image from a product link. Saved photos stay available offline, sync with the watch through iCloud, and travel with your JSON backups. YOUR OWN ICLOUD Changes save on your Mac first and sync through your private iCloud account. Use the same Apple Account on your Macs. There's no Crownlog login, subscription, or Rappasoft server holding your collection. BRING YOUR COLLECTION WITH YOU Import a JSON backup from the original Crownlog web app. Export a full JSON backup or a CSV for Numbers and Excel. The in-app guide and separate sample collection make it easy to try things out. Requires macOS 14 or later. iCloud sync requires an Apple Account with iCloud enabled. Online price checks and discovery run while the app is open and depend on public website access. Optional provider estimates require your own The Watch Info API key; no key is needed for manual estimates. Prices and converted totals are estimates, not appraisals. JSON and CSV exports are unencrypted.
