🐟 For freshwater, reef, shrimp, betta & more
Log a water test and Aquastat instantly tells you whether your tank is healthy, where the nitrogen cycle stands, and exactly what to fix — in plain language.
Why Aquastat
Every reading is compared against curated ideal ranges for your tank type. Aquastat never invents numbers — it just tells you what the water is saying.
Each parameter is graded good, watch, or out-of-range, then rolled up to a simple “is this tank good for its purpose?”
Reads your ammonia, nitrite, and nitrate to know if you’re not-started, cycling, or cycled — and whether it’s safe for livestock.
For anything off, a “why it matters” and “how to fix” — with advice that changes depending on your cycle stage.
Per-parameter history charts with a shaded ideal band, so you catch a slow drift before it becomes a problem.
A once-daily digest lists exactly which tanks are due for a water test, tuned to each tank’s cycle stage.
Your tanks sync across iPhone, iPad, and Mac through your own iCloud. No account, no ads, no tracking.
How it works
Pick your tank type, record any subset of parameters, and Aquastat does the rest — verdict, cycle status, attention list, and history.
