Identify marine species with AI, log your dives, share with fellow divers, and contribute to global reef conservation — all from your phone.


Point your camera at a reef creature and our AI identifies the species — name, family, conservation status — in seconds. Works in and out of the water.

Post encounters, follow fellow divers, and browse sightings from reefs around the world. Every post is automatically tagged with species and dive location.

Every photo is beautifully organised by species, location, and date. Build a living record of your life beneath the surface.

Log dive sites across the world on an interactive map. See where species have been spotted by the global Reef Tagger community.

Every tag contributes
to science
Anonymised sighting data from every dive is made available to verified marine researchers and government conservation bodies. Your dive log helps scientists track species populations, migration patterns, and reef health — at a scale impossible without citizen science.
