About

Aquarium Harmony is the calm, beautiful way to keep every fish tank thriving. Log water tests, build a care routine with smart reminders, and watch your aquarium come alive as a living, breathing picture of its real health - on iPhone, Apple Watch, and your home screen. Whether you keep a planted tank, a reef, a betta, shrimp, cichlids, or a classic freshwater community, Aquarium Harmony turns scattered notes and guesswork into one clear answer: what does my aquarium need today? A LIVING AQUARIUM, NOT A SPREADSHEET Every tank gets its own living world - water that brightens with good care and dims when maintenance slips. Three health rings show Care, Water, and Stability at a glance, with a full breakdown explaining every factor behind them.
