Wonder what that fish was? Dive Ledger includes 170 marine life species (fish, sharks, rays, turtles, invertebrates) plus 205 corals, sponges, and anemones. Every entry has a reference photo so you can match what you saw before the memory fades.
Log What You See
That manta circling overhead. The nudibranch hiding on the wall. Select species directly from the database and attach them to your dive log. Each sighting is saved with location, date, and conditions, so when someone asks "where did you see that?", you have the answer.
Build Your Underwater Life List
Birders have life lists. Now divers do too. Every species you log joins your personal marine life list. Watch it grow with every trip, from your first clownfish to your hundredth nudibranch.
Corals Count Too
205 corals, sponges, and anemones in the database. Staghorn, brain coral, table coral, sea fans. Identify and log the reef structures you see, whether you are documenting a reef survey or just curious.
