ReefDex: Dive Log & Species ID

ReefDex turns your phone into a marine biologist in your pocket.

Point your camera at a fish, coral, or invertebrate, underwater or from the boat, and the AI identifies it in seconds. Every result is cross-referenced against three scientific taxonomy databases (WoRMS, GBIF, and iNaturalist), so you get the accepted species name, its family, conservation status, and role in the reef.

Then ReefDex logs the sighting with GPS, time, and depth, and adds it to your personal dive history.

FOR SCIENCE
Every sighting you log adds a data point (species, location, time, depth) to a growing map of ocean biodiversity, so your dives help researchers and conservationists too.

Whether you scuba dive, freedive, snorkel, or are just curious about what lives on the reef, ReefDex helps you know what you saw and remember every dive.
