Everything your tank needs, in one app

Parameters & dosing

Log alkalinity, calcium, magnesium, salinity and more in seconds. See trends with target bands, get drift alerts before a parameter goes out of range, and calculate the exact dose to fix it.

Livestock & compatibility

Browse a built-in library of reef species. Before you buy, check any fish or coral against your own tank for aggression, reef-safety, adult size, and water needs.

Maintenance reminders

Never miss a water change, test, or dose. Recurring reminders keep your whole routine on track.

Private, and yours forever
