iPhone
Scan test kits with your camera for instant readings, and let Coach catch problems before you do. Health scores, livestock, and maintenance — with free iCloud sync.
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 No outdated design.
TEST KIT SCANNER
Point your camera at an API, Red Sea, or Salifert liquid test kit. AquaKeeper reads the colour against a reference card and logs the result for you — no more squinting at a colour chart or typing numbers by hand.
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.
SMART COACH
AquaKeeper watches your recent tests, livestock, and tasks, then flags what actually needs attention — a KH that's been sliding for days, nitrate trending up, a water change running late. Plain-language insights land in your Today tab, not a dashboard you have to interpret yourself.
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 — including a sidebar layout on iPad — with optimised layouts for both. Your data syncs automatically across all your Apple devices via iCloud at no extra cost.
