Most gear apps let you make a list. Some track weight. Kit Book does both - and tracks what your kit actually costs you over its entire lifetime. Buy a jacket for €400, sell it for €200, and Kit Book knows it cost you €200 - not €400. Across every item you've ever owned. That's your true kit cost, and no other app shows it to you. Log everything you own - backpacks, tents, crampons, skis, base layers - with weights, specs, ratings, and photos. Build packing lists for upcoming trips, mark items as worn or packed, use item sets to bulk-add grouped gear in one tap, and look forward to your upcoming trip with a photo and countdown on the home page. Browse the Research tab to explore thousands of community-reviewed gear items - filter by weight and price, read pros and cons, and add anything directly to your wishlist. Link to items you want to upgrade, and know the net cost of the exchange. Already have a spreadsheet? Import it directly. A community gear database pre-fills specs and reviews automatically, with AI filling in anything missing. Free up to 20 items, 1 trip, and 2 item sets. Pro unlocks unlimited items, trips, and item sets, plus photo backup, cloud sync across all your devices, and AI auto-fill. Terms of Use: https://kitbook.app/terms

Verdict
The clearest difference is in-app purchases: Platinum at none against Kit Book's 2. Platinum also leads on iOS requirement (12.0 vs 15.0). Kit Book's advantage is update cadence (every 5 days vs every 2 months). On price, ads and device support there is nothing between them.
