LYZO compiles data from water quality checks of all municipalities in France. It simplifies the interpretation of water analyses, allowing for more informed tap water consumption. Users can access their municipality's water quality and the history of recent health inspections.

Whether on vacation in a camper van or preparing infant formula, users can check water quality in different areas and be informed of any consumption restrictions. LYZO also reveals if pesticides are present, nitrate levels, water hardness, and the need for a water softener.

• *Health Information:** LYZO uses a simple color code to indicate water quality: green (compliant), yellow/orange (non-compliant), red (limited), black (restricted), with a health conclusion for each analysis. A dynamic glossary explains technical terms, and visual cues provide recommendations like running water before consumption or boiling it.
• *Additional Features:** Users can favorite municipalities, track various parameters over the past five years, view detailed analysis parameters with color-coded visuals, and access the number of analyses per department or percentage breakdown by color code.
• *Official Data:** LYZO utilizes public data from the Ministry of Solidarity and Health, updated monthly with a one-month delay. The app automatically fetches updates and resets data annually.
