Jumpbook — The digital logbook your jumps deserve. Log every jump with the detail it deserves, get them verified with in-person digital signatures, and share your progress with the world. AUTOMATIC JUMP TRACKING Put your phone in your pocket and jump. Jumpbook uses your phone's barometric sensor to detect exit altitude, freefall time, deployment altitude, and landing — automatically. VERIFIED DIGITAL SIGNATURES Get your jumps signed the way a paper logbook works — but better. A witness scans a QR code in person, and their credentials are permanently frozen with the signature. Instructors, coaches, licensed skydivers, and pilots each sign with their proper role. WIND & DRIFT ANALYSIS Real-time winds aloft, freefall drift simulation, landing pattern visualization, and safety alerts for crosswind and penetration conditions. SHARE YOUR JUMPS Turn any jump into a beautiful card with your stats over your favorite photo — ready for Instagram, WhatsApp, or anywhere. YOUR FULL SKYDIVING PROFILE Licenses and ratings with expiration alerts, currency tracking, emergency contact, gear details, and complete statistics of your progression. Whether you're working toward your A license or logging jump #5,000, Jumpbook keeps your skydiving history safe, verified, and always with you. Blue skies!
