AquaRoutine: Aquarium Care

Local water diagnosis, custom target ranges, incident and treatment logs, plus PO₄, Ca, Mg and TDS. Private aquarium care with no accounts.

AquaRoutine helps you care for your aquarium in a simple, private, organized way.

Record water parameters, get a clear diagnosis of what is happening, and keep up with maintenance routines—without an account or internet connection.

ON-DEVICE WATER DIAGNOSIS Based on your latest reading and your aquarium's target ranges, AquaRoutine tells you whether conditions are normal, need attention, or are critical; which parameters are affected; possible causes; what to do; what NOT to do; and when to test again. These are cautious rules calculated on your device: no servers and no remote AI.

TARGET RANGES FOR YOUR AQUARIUM Recommended profiles for freshwater, marine/reef, and brackish tanks, editable parameter by parameter and restorable with one tap. Your dashboard, charts, and diagnosis always use that aquarium's ranges.

THE PARAMETERS YOU ACTUALLY TEST pH, temperature, nitrate, ammonia, nitrite, GH, KH, salinity, and—when you use them—phosphate (PO₄), calcium (Ca), magnesium (Mg), and TDS. The form adapts to the aquarium type, so freshwater tanks are not asked for irrelevant values.

INCIDENT & TREATMENT LOG Record the issue, affected fish, medication, dosage, and dates. Mark the incident resolved when it passes and keep the history for next time.

ROUTINES & REMINDERS Water changes, feeding, cleaning, and maintenance, with configurable local notifications.

OFFLINE SPECIES REFERENCE 40 freshwater and marine species with photos, parameters, and compatibility guidance.

PRIVACY FIRST No accounts, no servers, no analytics, and no ads. Your readings, incidents, and photos stay on your iPhone. CSV, PDF, and local backup files are created only when you request them.

AquaRoutine provides general guidance based on your own target ranges; it does not replace advice from a veterinarian or qualified aquarium professional.
