Track your tank.
Share the journey
Fishkeeping is better with friends. Log water tests in seconds, stay on top of maintenance, and build a custom profile for your tank to share with other hobbyists.
From the people behind the Fish Tank World guides.
Built for the tank you actually keep
Freshwater-first, free, and quick enough that you'll still be using it in six months.
Ten-second water logs
Log a test from your phone in the time it takes to rinse the vial. Charts show the drift before it turns into a problem.
Knows what's safe for your fish
Readings are checked against the species actually in your tank, not a generic range. See at a glance when something's off.
Reminders that fit your routine
Water changes, filter rinses, dosing. Set the cadence once and we'll nudge you when it's due, then log it in a tap.
The whole story of your tank
Photos, notes, every fish you've added, every piece of gear you've swapped. From empty glass to today, in one timeline.
A custom profile for your tank
Photos, stocking, equipment, and specs on one shareable page. Give the people who get it something to look at.
500+ freshwater species, wired in
Care ranges, tank size, temperament, and compatibility, pulled straight into your stocking list and thresholds.
