A dive isn't a row of numbers. It's a memory — a path through the water, the wreck's story, the fish you can name now, what the ocean was doing that day. DeepSix Dive Log treats it that way. DeepSix Dive Log is native on iPhone, iPad, Mac, and Apple TV, with an Apple Watch Ultra companion. Your logbook lives on your devices and syncs through your own iCloud. No account. No DeepSix copy of your dive log. And it's free — the whole app. No dive cap, no ads. YOUR DIVE IS A PATH, NOT A PIN DeepSix extracts both entry and exit GPS from Shearwater dive computers — plotted together on the map, so a drift dive finally looks like what it was. Bluetooth download across 12 transport families, built on libdivecomputer; wired USB/serial import on the Mac; Garmin FIT and Suunto JSON too. Arm dive-day GPS tracking and the whole day becomes a route. Dives recorded on Apple Watch — the Depth app included — come in from Health and get their depth profile. WONDERS — WHERE THE OCEAN SHOWS OFF A curated catalog of remarkable underwater places, with real narratives — surfaced the moment a dive of yours lands near one. Each one contributed by DeepSix Dive Log divers. WRECKS, WITH THEIR WHOLE STORY 29,000+ curated diveable wrecks from national heritage registers on every continent, with offline coverage, historical dossiers, period-correct ensigns, and honest position-uncertainty rings. War graves are presented as something you honor, not trivia. Contribute corrections from inside the app; a person reviews every one. PHOTOS BECOME SPECIES Critter Expert identifies around 500 marine species entirely on your device — free, no account, no API key, no internet after a one-time 63 MB download. Region-gated, so it won't suggest a Caribbean fish in Palau, and nothing is ever confirmed for you. Names are verified against the World Register of Marine Species, with threatened-species status and invasive-species reporting built in — over time, your photos become a naturalist's logbook. Want the full range? Bring your own AI key (Anthropic or OpenAI) or a model on your own Mac — never a DeepSix charge. THE COLORS YOU ACTUALLY SAW Underwater photos come back blue. DeepSix knows how deep you were when you pressed the shutter, and whether the water was tropical blue, green or fresh, and restores the reds the water absorbed. Camera-aware, with GoPro red-filter compensation. Apply to one photo or the whole dive; corrections land in Apple Photos as revertible adjustments, never as copies. Video too, frame by frame as your depth changes. Free, on-device, nothing uploaded. WHAT WAS THAT DAY ACTUALLY LIKE? Tide state at your entry minute. Moon phase, sea temperature, swell, bleaching alerts, reef context from the Allen Coral Atlas and NOAA. Years later, the record answers what memory can't. Plus a 7-day conditions planner. BUILT HONEST Gas analysis that names its excluded dives. Deco shown as information, not alarm, when you dive tech. "Dives near" instead of inflated counts. Full-fidelity UDDF and Subsurface export, always free — lossless backup, the open .deepsixarchive format, and SQL and JSON exports any developer can build on. Your dive log will outlive any app, including ours. Smart Lists, gear and kits with service tracking, achievements, trips and a liveaboard planner round out the log. MacDive user? A high-fidelity import brings your dives, gear, photos, and dive-computer profiles across. FREE MEANS THE WHOLE APP Plankton, Whale, and Megalodon — the in-app purchases listed here — are optional Patron tiers that support the project. Their one perk is high-accuracy WorldTides tides; standard tides are free, or bring your own WorldTides key. DeepSix collects nothing unless you choose to send it: a wreck, a photo, a bug report. The privacy policy names every server we run and exactly what each one sees.

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.
