About this app

Gurglee is the smart logbook for aquarium enthusiasts—whether freshwater, marine, reef, planted, or brackish. Record your water parameters by speaking naturally—"calcium 420 in the reef"—and Gurglee automatically recognizes the parameter, value, unit of measurement, and tank. Just confirm with a tap, no tedious forms to fill out.

What’s new

No more starting from an empty app: on first launch you can open a sample tank that's already full, with two months of readings and one value out of range. It's labelled "Sample", stays on your phone, and one tap throws it away.

New accounts get their first 14 days with automatic sync: whatever you log goes up on its own.

Not sure how often to measure a parameter? We now tell you, based on your type of tank, with one tap to set the reminder.

AI answers can be read out loud.
