Frequently asked questions

Use the first slider to show how much fuel is left in your tank and the second for how many minutes you want to detour, and tap Calculate. For every station we work out what you save net compared to the nearest station: the price difference times your litres, minus the fuel the detour costs. We use real driving times on the road, so the station at the top gives you the most within that detour time, even when it is not the cheapest. If a station just outside that time gives clearly more, you see it below as a tip.

Prices come in all day long, but a station may have just changed its price. If you see a price that is wrong, report it through Help and feedback in Settings.

Go to Profile, Vehicle and tap Add vehicle. With a Dutch number plate the app fills in make, model and fuel by itself. With a Belgian, German or French plate, or no plate at all, you enter make and model yourself and choose the fuel. You can change tank size, consumption and your petrol type (E10 or E5) there at any time.

No, the fuel advice, the map and navigation also work without an account. With a free account your vehicles and saved addresses move with you to a new phone, and you can join Free fuel, notifications and reviews.

Yes. Tap Navigate at a station or search for a destination, choose your route and tap Start route; you get spoken directions, even with your screen locked. When you drive to a destination you searched for, you see the cheapest stations on your route and add a stop with one tap. If there is a traffic jam on your route in the Netherlands, the app tells you when another route is faster.

Yes, in the Netherlands the app warns you about speed cameras, red light cameras and average speed checks. During navigation and when you drive without a route with the app open, you hear a tone with the distance and, for a speed check, the speed limit. On an average speed check you see your average speed and you hear it when it is too high.

In the Netherlands you see traffic jams and roadworks on the way, and you see and hear accidents, closed roads and drivers going the wrong way, plus the speed limits and closed lanes on the overhead signs. When you choose your route you see the delay from traffic jams, and navigation drives around closed roads. With your car in Profile you also see which low emission zones you may enter.

Every day you tap Hopper in Free fuel until he pops and you collect tickets for the draw at the end of the round. You get extra tickets when you arrive at a fuel station with the app's navigation, even if you do not fill up, and when you share a deal, invite a friend, play seven days in a row or write a review that we approve. You can join with an account from age 18, in the countries where a round is running.

In Settings, Notifications you switch on or off, among others, the price alert, the weekly price summary, Time to fill up, Free fuel and review requests; for this you need an account and permission for notifications. We do not send the price alert, the weekly price summary or Free fuel reminders between 10 pm and 6 am. The price alert looks at prices near your home address (Settings, Location), and the weekly price summary arrives on the day and at the hour you choose, unless you already got another notification from us that day.

When you choose an electric car, the map shows the charging points in the Netherlands with the price per kWh and how many are free. That price is the operator's tariff, without VAT. What you finally pay depends on your charging card.

After a visit to a station Hopper asks how it was, in the app or with a notification, and you give stars with a short text if you like. We check every review before it appears at the station. You need an account for this, and once a review is posted you can no longer change it.

When you log in, tap Forgot password? and enter your email address. You get a code of 6 digits by email; enter it in the app and choose a new password. If you are logged in, you change your password in My profile.

Go to Profile, Settings and tap Delete account at the very bottom. Your account is then gone straight away; this cannot be undone. We keep some of your data for a while, such as feedback without your email address and Free fuel data. Which data and for how long is on the Delete account page.

We use your location to work out stations, prices and routes near you. We measure how busy stations are anonymously. How the app is used, we count separately from your account, with a code for your installation. We do not sell your data. Everything is in the privacy policy under Settings, Privacy.
