Curious what you saw on your dive? Loggerhead helps you find out.
Built for scuba divers and ocean enthusiasts, Loggerhead is a precise fish and marine species guide. It pairs a comprehensive taxonomic database with a purely functional, minimalist interface, giving you a reliable way to identify marine life and explore reef ecosystems. Add photos or videos from a dive, and Loggerhead suggests the closest match for each animal.
IDENTIFY MARINE LIFE
Browse over 10,000 species by animal group or taxonomic family. The database includes photos, how to tell look-alikes apart, and where they live. Animals that can sting, bite, or cut are clearly marked with what to watch for. Dive hand signals are included as well.
LOG YOUR TRIPS AND DIVES
Group dives into trips, pick the site, and note your depth, time, and gear. Have a paper logbook? Photograph a page and Loggerhead fills in the dive details for you.
PLAN YOUR NEXT TRIP
Find dive destinations on the map. Check the water temperature month by month and see which animals are around during different seasons.
DIVE WITH YOUR BUDDIES
Invite your buddies, tag them on dives, and see what they found. Only buddies you add can see your dives, and you can hide your activity at any time.
LEARN A LITTLE EVERY DAY
Take a daily quiz, read good news from the ocean, and watch your own virtual loggerhead turtle hatch and grow as you dive.
FREE SCANS
New divers get 20 free scans. A scan is one photo or one video frame, and you can buy more in packs in the app. Logging dives, planning trips, and browsing the species guide are completely free.
Available in English and Spanish.

Loggerhead is now available in Spanish. This version also lets you scan one of your photos again from its species page, remove a species from a whole trip at once, and fixes a few bugs. Happy diving!
