Circle K Easy Fuel is a free iPhone app developed by Circle K AS. It falls under the Lifestyle category and specifically the Shopping subcategory. The app allows you to refuel your car quickly and easily without having to use your payment card or enter a PIN code.

To use the app, all you need to do is drive up to a Circle K gas station, and the pump will automatically open when it reads your license plate. The app will then charge your registered payment card for the fuel you pump. You can also set your location services to "always" to make the process even smoother.

Circle K Easy Fuel is easy to use, and you can register as a new user or log in with your Circle K EXTRA account. The app is secure, and similar technology is already used for parking garages, toll roads, and mobile payment solutions.

Overall, Circle K Easy Fuel is a great app for anyone who wants to save time and effort while refueling their car.
