About this app
Oceanus is a scuba diving logbook and an AI marine species identifier in one app. Log every dive, then point your camera at a fish and find out exactly what you just saw. Built for scuba divers, freedivers and snorkelers.
🤿 SCUBA DIVING LOGBOOK
Keep a complete dive log for every dive you make:
• Max depth, average depth and bottom time
• Full depth profile chart for each dive
• Dive site name and map location
• Water temperature, visibility and water type (salt, fresh, brackish)
• Wetsuit, semi-dry or drysuit, tank type, start and end pressure
• Personal notes on every dive
• Scuba diving and freediving logged side by side
⌚ IMPORT FROM YOUR DIVE COMPUTER
Import dives straight from a Garmin dive computer. Drop in a FIT file from your
Descent and the whole dive — depth profile, duration, temperature — lands in your dive log with no retyping.
📷 AI SPECIES IDENTIFICATION
Point your camera at a fish, shark or ray and get the top matches instantly, with a confidence score and what sets each species apart. Works on a dive, at the aquarium, or from your snorkeling photos.
🔗 LINK SPECIES TO DIVES
Tag the species you identified to the dive you saw them on. Your dive log stops
being a table of numbers and becomes a record of what actually lives down there.
🐠 284 SPECIES, HAND-ILLUSTRATED
Fish, sharks, rays, marine mammals, invertebrates and more. Every species profile carries the scientific name, depth range, geographic regions, danger level and conservation status — so you know what is safe to approach before you get in the water.
📊 YOUR DIVING STATS
Total dives, hours underwater, deepest dive, species collected, 34 achievements to unlock. Watch your logbook and your collection grow together.
☁️ CLOUD SYNC
Sign in with Google and your dives, species and favorites follow you to any
device. Change your phone, keep your logbook.
WHO IT IS FOR
Scuba divers who want a dive log that is faster than paper and smarter than a
spreadsheet. Freedivers and spearfishers tracking depth and bottom time.
Snorkelers who keep asking what that fish was. Marine biology students, aquarium hobbyists, and anyone who would rather know than guess.
WHY OCEANUS
Most diving logbook apps stop at the numbers. Most fish ID apps ignore the dive. Oceanus does both, so the species you identify and the dive you identified them on live in the same place — with an ocean-themed design that is actually pleasant to open after a day on the boat.
