About Lagoon: Dive Log & Logbook
A logbook that feels like a memory, not a form. After a dive, the last thing you want is a form to fill out. With Lagoon, you just talk. Describe your dive out loud - the wreck you found, the turtle that swam past, how cold the water was - and Lagoon turns it into a clean, complete log entry: site, depth, duration, conditions, and the story, all in one place. Built for the vacation diver, not the logbook nerd. Lagoon is made for the diver who dives 10-50 times a year on trips, not the technical diver tracking every gas mix. It's fast, it's forgiving, and it makes your dives worth looking back on. What Lagoon does for you: - Voice-to-log: speak after a dive and Lagoon writes it up for you, tagging species and milestones as it listens - Auto site detection: Lagoon uses your location to suggest the dive site, no typing required - A dive card for every dive: a beautiful, shareable summary, perfect for your dive buddies or your feed - Your whole dive world: browse your logbook as a list or spin the globe to see everywhere you've been - Full data ownership: export everything, anytime - your dives are yours - Light gear and certification tracking, so you don't need three apps Free to start. Lagoon is free to download and log your dives. If you want unlimited dives forever, unlock it once for $19.99 - no subscription, ever. Made by a diver, for divers. Lagoon is built by a small, independent team who would rather you remember your dives than manage them.
