SeaLog: Dive Log & Logbook
The dive log that fills itself in
SeaLog is the dive log that fills itself in. Connect your dive computer over Bluetooth, download your dives, and your logbook is already written by the time you're back on the boat. No more retyping depth, bottom time and gas mix into a form after every dive.
Your dives arrive by themselves, over Bluetooth from Shearwater, Suunto, Scubapro, Mares, Oceanic, Aqualung, Cressi and dozens more, from UDDF, FIT and CSV exports of any desktop log, or straight from Apple Watch Ultra and Garmin Descent through Apple Health. Every import is matched against what you already have, numbered correctly and merged without duplicates.
Then it gives you numbers that actually mean something: bottom time, max depth, gas mixes, coldest dive, countries dived, and a SAC rate with a trend that tells you whether your air consumption is really improving. Build your own dashboard from 27 cards, scrub through depth and temperature profiles, and see every dive site on a map. Log the shark, turtle, manta or nudibranch you saw and grow a life list with your firsts highlighted, then watch your Dive Passport fill up with countries and stamps you can export and share.
Your logbook syncs to your account, so a lost phone is never a lost logbook, and export in UDDF, CSV and PDF is free on every plan. Sign in with Apple, Google or a one-time email code. SeaLog is free to start; SeaLog Pro unlocks an unlimited dive log, unlimited marine life sightings and the full Dive Passport as a monthly, yearly (7-day free trial) or one-time lifetime plan.
