Everything you need to know about getting the most from Fillzz.
Fillzz aggregates prices from official sources, station operators, and daily community updates. We verify each data point before it appears in the app so you can compare prices with confidence.
We currently cover France, Spain, Italy, Portugal, Andorra, Switzerland, and the United Kingdom. More European countries are planned-follow @fillzzapp for updates.
Fillzz supports Diesel (B7/B7+), Unleaded 95/98, E10, E85, LPG, CNG, LNG, Hydrogen, and Biodiesel blends. Use the fuel selector to switch instantly between fuel types.
Follow a station by tapping the heart icon, then set a price target from the station detail screen. Fillzz sends a push notification as soon as the station drops below your target or publishes a lower price nearby.
Open the station, tap “Report price”, and share the correct amount. Include a receipt or photo if possible. Our moderation team reviews submissions quickly to keep the database accurate for everyone.
