Tank Mate: Aquarium Care

From reef to freshwater: track water, photograph your tanks, log inhabitants, and plan your next water change. Your aquarium life, together.

Every aquarium has a story. Keep yours together with Tank Mate.

Track water quality, care routines, inhabitants, and photos in one app for freshwater, planted, marine, and reef aquariums.

YOUR TANKS, ORGANIZED Give each aquarium its own photo, water tests, notes, reminders, and inhabitant log.

SEE CHANGES OVER TIME Choose your parameters, set ideal ranges, and explore interactive graphs with pinch-to-zoom and exact reading selection.

TOOLS BUILT FOR AQUARIUM KEEPERS Plan water changes with evaporation and a finishing reserve. Calibrate salt-mixing estimates to your own salt and scoop. Calculate aquarium, sump, and refugium volumes, account for rock and sand displacement, and estimate sand-bed requirements.

KEEP TRACK OF YOUR INHABITANTS Search common-name suggestions or add your own. Record quantities, photos, observations, and moves between tanks, with advisory compatibility notices for supported species.

YOUR RECORDS, YOUR CHOICE Work offline, enable optional private iCloud sync, or export a separate backup with photos. Available original Tank Mate records migrate automatically when you update.

Make it yours with light and dark appearance, accent colors, and matching app icons.

No subscription. No separate Tank Mate account.
