About this app

LYZO © lists the data of the sanitary controls of the water distributed by all the municipalities of France.

Water analyzes are complex and often difficult to decipher, LYZO simplifies their reading and allows you to consume tap water more wisely.

You will know the quality of the water in your municipality as well as the history of health checks in recent months.

On vacation, you travel by motorhome, you will know the quality of the water of the different municipalities, drinking water points.

You use tap water to prepare your baby's bottle, you will know if there are any consumption restrictions.

No internet connection required, all data is stored on your smartphone.


LYZO indicates via a very simple color code the quality of your tap water: compliant (green), non-compliant (orange), limitation (red), restriction (black). For each analysis, you have the health conclusion and the details of the measurements (nitrate, pesticide, lead, etc.).

An additional visual can indicate recommendations:
- Let the water run before drinking it
- Boil the water before drinking it
-The water may have an awkward smell, color or taste
-Reconsider the consumption of selenium-based dietary supplements
