The aquarium app that actually does the work.
Scan fish. Test water. Simulate stocking decisions. Track everything — without the spreadsheets, the forum trawling, or the guesswork.
What App-aquatic does
Six core capabilities built to replace the guesswork at every stage of fishkeeping.
Species scan
Point your camera at any fish for instant identification — species name, care requirements, temperament, and ideal water parameters in one scan.
Illness detection
The illness scan analyses visible symptoms and flags the most likely conditions with clear, actionable treatment guidance — no forum trawling needed.
AI strip scanner
Scan any test strip with your camera and get instant parameter readings. Works offline, always free — use pre-calibrated kits or build your own.
Tank simulator
See the exact impact of adding a new fish before it enters your tank — bioload, pH and temperature compatibility, aggression, and swim space checked instantly.
Water tracking & history
Log every test result with your camera. Build a full parameter history — spot trends before they become problems and see what's changed over time.
Tank ledger
A complete timestamped record of every test, water change, fish addition, and maintenance task — maintained automatically as you use the app.
Depth without complexity.
Fishkeeping is a genuinely deep hobby. Water chemistry, species behaviour, bioload, disease management — there's a lot to understand. Most apps either dumb it down so much they're useless, or throw all the data at you with no guidance.
We built App-aquatic to hold both. The surface is simple — scan, log, check. Underneath, the maths, the compatibility analysis, and the AI work hard so you don't have to.
Built by aquarists. Tested on real tanks. Designed to be the only app you need.
