AquaKeeper — Fish Tank Tracker

The cleanest aquarium tracker on iOS. Health scores, water test charts, livestock, and maintenance — with free iCloud sync. Built by a hobbyist.

Track every tank. Catch problems early. Never miss maintenance.

AquaKeeper is a clean, fast aquarium management app built by a hobbyist who was frustrated with existing options. No bloat. No outdated design.

WATER TEST LOGGING Log pH, ammonia, nitrite, nitrate, phosphate, calcium, alkalinity, magnesium, salinity, and temperature. Beautiful charts show trends over 7, 30, 90 days or all time. Safe-range lines tell you instantly if a parameter is off. Tap any data point for the exact reading.

HEALTH SCORES Every tank gets a 0–100 health score calculated from your recent water tests. See at a glance which tanks are thriving and which need attention — before small problems become expensive ones.

LIVESTOCK TRACKER Log every fish, coral, and invertebrate with species name, purchase price, date added, and current status. Browse 200+ species with care guides, minimum tank size, temperature and pH ranges. Compatibility warnings alert you before adding a new inhabitant that may conflict with your existing livestock.

MAINTENANCE SCHEDULER Create recurring tasks for water changes, filter cleanings, media replacements, and anything else your tank needs. The Today tab shows all overdue and due-today tasks across every tank in one view. Push notifications remind you before tasks slip.

EQUIPMENT LOG Track pumps, lights, skimmers, heaters, and reactors. Log purchase date, price, and warranty expiry. Get highlighted warnings when warranties are approaching. See your total equipment investment per tank.

PHOTO LOG Document your tank's journey. A photo timeline shows how your aquascape and corals have grown over months and years. Tap any photo for fullscreen view with pinch-to-zoom.

iPHONE AND iPAD AquaKeeper works natively on iPhone and iPad with optimised layouts for both. Your data syncs automatically across all your Apple devices via iCloud at no extra cost.
