Gurglee: Aquarium Logbook

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.
