Updated July 2026. Covers all shallow-water reef fish commonly seen by snorkelers (and some rare ones too). Flip through screens like pages of a book, or find a fish quickly by color or shape. Up to 5 photos per fish—showing juveniles, males, females, color variations. Videos of each fish too. Save fish you've seen in the Log Book. Sharpen your fish ID skills with flashcard-style Quiz Mode.
- For snorkelers and beginning scuba divers.
- 205 species** / 600+ photos!
- Identify fish by color, shape, family group, or name (common, scientific, Hawaiian).
- Multiple photos of most fish.
- Flashcard-style quiz.
- Videos of all fish (requires internet).
- Logbook: save fish, add notes, share Logbook (text only).
- Links to Fishbase and Reef.org for each fish.
- Works great on iPads too.
** Only half of Hawaii's 400+ shore fish live at snorkeling depths. For easier ID, faster download and smaller footprint, this app omits deeper-dwelling fish. For a more complete set of fish, see my app Scuba Fish Hawaii.
