Features
Everything for your logbook, in one app
Log water values
Enter a test session in seconds — pH, KH, nitrate and more, with your own target values.
See trends
A chart per parameter with a target band, so you spot deviations before they become a problem.
Reminders
Water change, testing, feeding — scheduled locally on your device, no server involved.
Inhabitants & equipment
Who's swimming around and what's running — with photos and notes per inhabitant.
Sharing
Show off your aquarium — if you want to
Optionally connect your ohhi.nl account and share a public page of your aquarium: current water values, inhabitants and photos, through a single link.
Turn the page off whenever you like — the link stops working right away. Without the connection, everything simply stays local on your device.
