SeaLog is the scuba dive log that fills itself in. Connect your dive computer, import your dives, and your logbook is done before you have dried off. IMPORT FROM YOUR DIVE COMPUTER Your dive computer already recorded the dive. SeaLog reads it. Import from Suunto, Shearwater, Oceanic, Aqualung, Scubapro, Mares and Garmin, over Bluetooth or from a file. Bring across a whole diving history in one go from PADI, SSI, DiverLog, Divelogs, Subsurface or any UDDF file, and pull dives logged on Apple Watch straight from Apple Health. A 300 dive logbook lands in your pocket in about a minute, with depth profile, bottom time, temperature and gas mix intact. A REAL SCUBA LOGBOOK, NOT A NOTES APP Every dive log entry holds what a diver actually records: max and average depth, bottom time, surface interval, tank and gas, weights, exposure suit, visibility, current, water and air temperature, buddy, dive center and instructor. Add photos and video to any dive log. Your diving logbook works offline on the boat and syncs the moment you find signal, so a week of liveaboard diving is never lost. DIVE SITES YOU DO NOT HAVE TO TYPE Nearly 5,000 dive sites are already in the app, from the Red Sea to Raja Ampat to your local quarry. Pick the site and the scuba dive log fills in the name, the coordinates and the map. Missing one? Add it, and it stays in your logbook forever. YOUR MARINE LIFE LIST Log what you saw, not just how deep you went. The Seadex is a life list for scuba divers: tag species on a dive log entry and build a personal record of the marine life you have met underwater. Hundreds of species with photos, ranges and identification notes. DIVING STATS THAT MEAN SOMETHING Total dives, hours underwater, deepest dive, favorite dive site, air consumption trends, certifications and their expiry dates, insurance and its renewal. Your diving progress in one screen, ready when a dive center asks to see your dive log book. DIVE WITH YOUR BUDDIES Follow the divers you actually dive with. Their dives appear in your feed with the depth, the time and the photos. Share a dive with a buddy and it lands in their scuba diving logbook too, with both of you credited. Your public profile is opt in and off by default: nothing is shared until you say so. FREE, AND PRO WHEN YOU WANT IT Log 3 dives and 3 species for free, with every import source and every dive site included. SeaLog Pro unlocks an unlimited scuba dive log, the full Seadex, unlimited photos, PDF and UDDF export, and cloud backup across iPhone, iPad and Apple Watch. One purchase covers every device you sign in on. WHY DIVERS SWITCH TO SEALOG Paper log books get wet and get lost. Manufacturer apps only read their own dive computer, so a diver who has owned a Suunto and then a Shearwater ends up with two half logbooks. SeaLog reads all of them and keeps one diving log for your whole life underwater, from your first open water dive to your thousandth. Export it whenever you want, in a format other dive log apps can read. It is your dive data, not ours. BUILT FOR EVERY SCUBA DIVER Open Water divers logging dive number four. Divemasters and instructors tracking hundreds of dives a season. Technical divers with trimix, deco stops and multiple gas switches. Freedivers and snorkelers who want the same species life list. If you go underwater, SeaLog is your logbook. LOOKING FOR ONE OF THESE? A dive log app that syncs with an Oceanic dive computer. A scuba diving log that reads Suunto. A dive tracker for Apple Watch. A scuba dive journal with photos. A diving logbook app that exports to UDDF. A free dive logbook to replace a soaked paper log book. A scuba diving log book your instructor will sign off on. SeaLog is all of them, in one dive log. Metric or imperial, your choice, switchable at any time.
