Simple and practical, a reference app for the maintenance and control of our aquarium. It lacks some intuitiveness when using it but you get used to it quickly. I would improve the fish and plant counters.

Jose Alonso


Simple to use application, very visual and of great help to keep control of the parameters of our aquariums. If you add more capabilities it can become a great application.



The best application to keep everything related to your aquariums up to date. 10/10

Marcos Pardo


App with many possibilities and that all aquarists will like. If it is polished, it will be an essential app since there are not many like this.



Great application to control the aquarium values and to take care of some species
