Stop guessing. Start knowing what your tank needs.
AquaKeeper tracks every water parameter, feeding, and maintenance task — so your fish stay healthy and your tank stays balanced. The only aquarium app that actually keeps up with you.
Everything your aquarium needs. Nothing it doesn't.
Water Parameter Tracking
Log pH, ammonia, nitrite, nitrate, temperature, GH, KH — every reading in seconds. See trends over weeks and months with clean visual charts. AquaKeeper flags dangerous values based on your specific species, not generic ranges. Spot a problem before your fish show symptoms.
Species-Aware Care
AquaKeeper knows your stock. Add your fish and it automatically adjusts safe parameter ranges, feeding guidelines, and compatibility warnings. Keeping tetras with cichlids? You'll know before it's a problem.
Growth & Breeding Tracker
Track each fish's size over time. Log breeding pairs, fry counts, and growth milestones. Whether you're a casual hobbyist or a serious breeder, every detail is recorded and visualized.
Health Monitoring
Notice something off? Log symptoms, track treatments, and keep a full medical history per fish. When you dose medication, AquaKeeper tracks the treatment window and reminds you when it's time for the next step.
Smart Maintenance Reminders
Water changes, filter cleaning, dosing schedules, light timers — set it once, get reminded every time. Customize intervals per task, per tank. Your routine runs itself.
Multi-Tank Dashboard
Freshwater, saltwater, planted, breeding — manage them all from one screen. Each tank gets its own parameter history, stock list, and maintenance schedule. Switch between tanks in one tap.
