Common questions

Why is a station grey?

Its price has not been confirmed for more than a week. Grey stations stay on the map and in the list, but they are left out of the price comparison and sorted after stations with a current price. The date shown with each price is the day it was last reported.

Why can't I find a station?

Stations with no price reported for thirty days are hidden until a new price arrives. Also check the fuel filter, since a station that does not sell the selected fuel is not shown, and the search radius of 5, 10, 20 or 50 km.

A price is wrong

Prices are collected from public reports several times a day, and each one shows the day it applies to, so a station may have changed its price since. If a price is clearly wrong, tell us the station and the fuel and we will look into it.

How does Tankuj use my location?

Only while the app is open, and only to find stations around you. Your position is sent to our server with the search and is not stored. If you do not allow location access, the map opens on the whole of the Czech Republic: pan to the area you want and tap “Search this area”. The privacy policy has the details.

How do I see the price of a full tank?

In Settings, enter your tank volume in litres. Every station then also shows what a full tank costs there.

How do I change the navigation app?

In Settings, choose Apple Maps, Google Maps, Waze or Mapy.com. Tapping Navigate on a station then opens it in that app.

Does Tankuj work with CarPlay?

Yes. With your iPhone connected to the car, Tankuj shows the cheapest stations around the car on its display, with a fuel switch and sorting by price or distance. Navigation to the station you pick is handed to Apple Maps.

Which iPhone do I need?

Tankuj requires iOS 26 or later.
