What the app does
I Saw a Fish is a marine fish catalog and observation logbook for scuba divers, snorkelers, freedivers and ocean enthusiasts. Browse a photo catalog of over 2,600 tropical reef fish species, search by name or family, and record what you saw on each dive with the date and location. The species catalog works offline, so it is usable on a boat or a remote reef with no mobile signal.
