Snorkel Fish Hawaii for iPhone is a comprehensive mobile application designed for snorkelers and beginning scuba divers. Updated in September 2023, this app covers a wide range of shallow-water reef fish commonly encountered in Hawaii, including some rare species. With an extensive database of 205 species and over 600 photos, users can easily identify fish by color, shape, family group, or name, be it common, scientific, or Hawaiian.

The app allows users to browse through fish profiles like pages of a book, search for fish based on color or shape - a unique feature not found in other fish apps. Each fish entry includes up to 5 photos showcasing juveniles, males, females, and color variations. Additionally, users can test their fish identification skills with the flashcard-style quiz and watch informative videos for each fish (internet connection required).
