Tank Buddy: Aquarium Care

Keep every tank healthy: log water tests, track fish & plants, get maintenance reminders, and watch your aquarium's progress over time.

Tank Buddy is the easy way to care for your aquariums — freshwater, saltwater, or brackish.

Whether you keep one betta or a room full of reef tanks, Tank Buddy helps you stay on top of the maintenance that keeps fish healthy and water pristine.

FEATURES • Multiple tanks — track every aquarium in one place, with type, volume, and setup date. • Livestock — log your fish and plants, with a built-in species database and compatibility warnings so you don't mix the wrong tank mates. • Water testing — record pH, ammonia, nitrite, nitrate, KH, GH, temperature, and salinity, and see trends on easy line charts. • Water changes — log every change and see at a glance when a tank is overdue. • Maintenance reminders — schedule recurring tasks (water changes, testing, feeding, filter cleaning) and get on-device reminders when they're due. • Progress photos — build a timelapse of each tank as it grows in. • Calendar — every event and due task in one view. • Cloud sync — your data syncs securely across your devices, and works offline.
