Reef Notes
Reef tank log & AI photo ID
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Snap a photo to ID a fish, diagnose disease or read your test kit. Log every parameter, catch bad trends early, and keep your reef on track.
Reef Notes is the logbook for saltwater and reef aquarium keepers - everything you record about your tank in one place, plus AI that actually helps.
TRACK YOUR TANK
- Water parameters with trend charts: salinity, temperature, pH, KH, calcium, magnesium, ammonia, nitrite, nitrate, phosphate, plus your own custom parameters
- Livestock list that warns you about compatibility when you add a new fish or coral
- Maintenance schedule with reminders, feeding log, dosing log and running cost
- Photo timeline so you can see how the tank has grown
AI PHOTO TOOLS
- Species ID: point your camera at a fish or coral and find out what it is
- Disease diagnosis: photograph a sick fish and narrow down what is wrong
- Test-kit reading: photograph your color card and get the number, calibrated to your own kit
- Aquascape and lighting advice from a photo of your tank
- Dream Tank: describe the tank you want and get an AI concept render
KNOW WHAT TO DO
- 3,000+ species with water requirements, temperament and reef-safe notes
- 180+ care articles, from cycling a new tank to chasing algae
- A 30-day cycling plan that tells you what to do each day, from empty tank to first fish
- Disease library with human-reviewed treatment plans
- Smart water alerts that spot a bad trend before it becomes a problem
SHARE YOUR TANK
Post a photo to Fish Friends and see what other people are keeping. Every post is reviewed by a person before it appears.
YOUR DATA STAYS YOURS
Your tanks, tests and photos live in your own private iCloud database and sync across your devices. We never receive them. No ads, no tracking, no third-party analytics.
A NOTE ON MEDICATION
Reef Notes deliberately never generates dosages or concentrations. Getting those wrong kills livestock. For treatment we point you to the human-reviewed entries in the Disease library and to the instructions on the product you actually own.
