Keep an eye on your tank
Log your measurements, follow the trend of every parameter and get alerted when a value starts to drift.
One tank free for life.
Tracking a tank: today's health, latest measurements and a curve for every parameter.
Tracking your tank gets simple.
On paper, connecting your measurements and spotting a trend quickly gets messy. Here, everything lines up on a graph on its own: at a glance, you see exactly where your tank stands.
How it works
You log your measurements
Enter your tests in a few seconds.
You see the trend
Your measurements plot on the graph.
You get alerted
An alert warns you of any drift.
What you can track
Measurements and events, on one graph
Add your tests and your maintenance actions, and find everything on the same graph. Each parameter shows its optimal range: you spot right away what's off.
The big picture, thanks to the calendar
All your tests and maintenance show up on the calendar, with a year view that reveals how consistent you are.
Your livestock and its breeding
List your fish, shrimp and plants: species, counts, morphs. Track arrivals, losses and spawns, generation after generation.
One tank, or your whole fishroom
Switch from one aquarium to another in a tap. Each has its own profile, today's health and its next test due.
And everything else
Everything to manage your tanks, and an app that bends to the way you work.

Frequently asked questions
How many aquariums on the free plan?
One, with no time limit, including tracking, curves and alerts. Premium unlocks unlimited tanks, budget and breeding.
Do I get my tanks on all my devices?
Yes. Your account is synced: phone, tablet and computer, always up to date.
Can I track my own parameters?
Yes. Pick a ready-made profile (planted, shrimp, reef…) or build your own, with the parameters and ranges you want.
Can I use it for saltwater?
Yes. Besides freshwater, shrimp and planted tanks, there are ready reef profiles (soft corals, SPS/LPS), and you can create your own.
Does my data belong to me?
Yes, entirely. No lock-in: your data is yours, viewable and exportable to CSV at any time.
Does the app show ads?
No, none. The model relies on the Premium subscription, not on advertising.
