Fin is more than a dive logbook. It maps over 27,000 dive and snorkel sites worldwide, each with depth ranges, water temperature by month, the species you can expect to see, and the operators nearby, so you know a site before you go. ◆ Discover sites: Search over 27,000 dive and snorkel sites around the world by location, skill level, entry type, and the species you want to see. ◆ Plan your next dive: Get depth, visibility, water temperature month by month, hazards, and nearby operators for every site, and find dive sites near you. ◆ Identify marine life: Look up any species to see where it has been logged and when it is most active. Not sure what you saw underwater? Describe it and Fin suggests matches from real logged sightings. ◆ Log every dive: Record depth, conditions, gear, and the species you spotted, then look back at your dive history on a map of your own. ◆ Build your collection: Track how many species you have seen and earn badges for milestones as your collection grows. ◆ Follow other divers: See divers' public profiles, follow the logs you find useful, and build a following of your own. ◆ Share your dives: Post your sightings and dive cards to friends and social. Fin is for anyone who dives, snorkels, or freedives. For weekend shore dives and once-in-a-lifetime liveaboards. Whether you are chasing your hundredth wreck or spotting your first reef fish, there is a site out there for you. Fin has no ads, no sponsored placements, and no fabricated data. If we do not have a verified answer, we say so rather than guess.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Map filters now match the website: an activity legend that shows what each pin colour means, a Map and Satellite toggle, and a live count of the sites in view. Tapping a site in the list opens it. The list panel drags smoothly. Site pages no longer jump while you scroll, and the species categories fit the screen properly.
