Dyvo is a dive logbook that treats your dives the way you remember them — not rows in a spreadsheet, but places on a globe. EVERY DIVE ON THE GLOBE See your whole diving life on a beautiful satellite globe. Every site you've splashed gets a pin — spin the earth to relive past trips, and drop pins for the dives you're planning next. A LOGBOOK BUILT FOR DIVERS Capture everything that matters in seconds: max and average depth, bottom time, water and air temperature, visibility, current, surface conditions, gas mix (air, nitrox, or trimix), tank size and pressures, suit and weight, boat or shore entry, operator, buddy, and the marine life you spotted. Add photos and notes so every dive is a story, not just a stat. BRING THE LOGBOOK YOU ALREADY HAVE Import UDDF from Shearwater Cloud, Subsurface, Diving Log and more, or pull underwater workouts from Apple Health if you dive an Apple Watch. Imported dives keep their full depth profile chart. PLAN THE NEXT ONE Pin a future dive and Dyvo forecasts the site: a divability score from swell, period, wind, current and rain; slack windows and current set from NOAA stations; tides; sunrise and sunset in the site's own time zone; estimated visibility from five days of weather. Marine warnings are free for everyone, on every dive, always. BADGES THAT KNOW YOUR HISTORY 60 badges across depth, gas, conditions, marine life, travel and habit, judged against your whole logbook — an import awards everything you already earned, each pinned to the dive that unlocked it. Spin the medal in 3D and read the engraved back. YOUR DIVING, BY THE NUMBERS A dashboard that turns your logbook into milestones: dive count, time underwater, depth records, SAC rate, depth trends, marine life and the regions you've explored. Close out any year with a Year in Review card from your photos. Metric or imperial, your choice. GEAR AND C-CARDS Track your kit with serials, purchase dates and service intervals, and the dives on that reg since its last service. Certification cards store scans of both sides and open offline — the only way that's useful at a shop counter. DIVE BUDDIES, NOT FOLLOWERS Dyvo has no public feed, no follower counts, and no user search. You connect by sharing a personal invite link with people you actually dive with, and choose exactly which dives to share. Shared dives travel through iCloud's private sharing — visible to your buddies and no one else. Log the same dive as a buddy? Link the two and read both logs together. PRIVATE BY DESIGN Sign in with Apple. Your logbook syncs through your personal iCloud, and your photos are stored in full inside it — never shuffled off to someone else's server. No ads. No tracking. ALWAYS WITH YOU • Home Screen widget with your logbook at a glance • Live Activity dive timer on the Lock Screen and Dynamic Island • Siri & Shortcuts — log a dive or ask for your stats hands-free • Buddies' shared dives cached on device, readable offline between dives DYVO PRO Free forever: unlimited dives, certification cards, all 60 badges, CSV export, and marine warnings.
