Your real tank, alive on your phone. When the water turns, you'll see it and know what to do. Add your tank, or snap a photo of it, and App-aquatic draws your own fish, plants and wood, swimming and swaying. Test your water and the tank reacts: it clouds over when something is wrong and clears when you fix it. YOUR TANK, ALIVE • Your own fish, shrimp, snails and plants, drawn and moving • Snap a photo of your tank and the app sets it up, down to the sand, rocks and wood • A bad test shows: cloudy water, and algae on the glass when you log it • Beet, your fish companion, warns you early, e.g. when nitrate is heading past 40 ppm • Tap the water to feed your fish, and share your tank as a picture SOS EMERGENCY HELP Fish gasping, sudden deaths, cloudy water, a broken heater? Tap SOS for "do this now" steps based on your latest test. AI FOR A SECOND OPINION • Identify fish and plants from a photo, with signs of illness • Tank health check and AI water test from one photo • Identify algae and follow a step-by-step plan with before and after photos • Fix My Tank: a 7-day recovery plan KNOW BEFORE YOU BUY • What If: see how a new fish changes bioload, water match and compatibility before you buy • Bioload from your real filter, not old inch-per-gallon rules • 800+ fish, shrimp and snails and 175 plants, with tank mates and group sizes • 150 tank models with sizes built in TEST WITH THE KIT YOU ALREADY OWN • Photograph your tubes beside the color card and tap each one: matched in seconds • API Freshwater Master Test Kit built in, plus popular strips from API, Tetra, JBL, sera and more • Another liquid kit? Teach the app its color card once • Log every test, several a day if you need to • Honest: a skipped test shows "not tested", never a fake "safe" zero • A green / amber / red verdict for every reading, judged against your own fish • "Do this first": the one fix that matters most, and how urgent it is CYCLE A NEW TANK • Cycle companion for fishless and fish-in cycles • The exact ammonia dose for your bottle's strength • Spots a stalled cycle (low pH or KH) and how to fix it • A 24-hour test that tells you when your tank is ready for fish CARE THAT ORGANIZES ITSELF • Reminders for water changes and filter, heater and pump care • Ledger: an automatic timeline of every test and event, with CSV export • History and charts for ammonia, nitrite, nitrate, pH, GH, KH, temperature, phosphate, TDS and chlorine • Calculators: water change %, tank volume, heater size, CO2, salt dose, hardness • Tap water baseline: chlorine, chloramine and nitrate explained • Several tanks, including quarantine; gallons or liters, °F or °C YOUR 14-DAY PREMIUM TRIAL Open the app and your 14-day Premium trial starts.

Verdict
The clearest difference is ads: App at none against ReefBay's shown. App also leads on review sentiment (94% vs 83%) and iOS requirement (13.0 vs 16.4). ReefBay's advantage is ratings volume (479 vs 17). On price, rating, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. ReefBay sells 4 in-app purchases, starting at $4.99 per month and App sells 5 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for ReefBay against 4.8 for App. That said, the two scores are not equally well evidenced: ReefBay has 479 ratings behind it against 17, so its average is the more settled of the two. Written reviews are what separate them: 83% of ReefBay's written reviews are positive against 94% of App's.
ReefBay ships an update every 8 days, App fortnightly. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
