Scuba Fish Hawaii, developed by John P Hoover, is a comprehensive marine life identification tool designed for scuba divers and advanced snorkelers. Updated in September 2023, this app covers 366 fish species commonly seen underwater, with a total of over 950 photos available for reference. Users can easily identify fish by color, shape, family group, and name, whether common, scientific, or in Hawaiian terms. The app also offers videos of each fish (internet connection required) and a new flashcard-style quiz mode to enhance fish identification skills.

For users' convenience, Scuba Fish Hawaii provides links to Fishbase and Reef.org for detailed information on each fish species. Additionally, the app features a Logbook where users can save fish sightings, add notes, and share their log with others. Compatible with iPads, this app is a valuable resource for marine enthusiasts seeking to explore and understand Hawaii's underwater world.
