Which Android app should I use to pay for gas and get a discount without having to go inside the store?

7 is designed specifically for this modern refueling and convenience store scenario. The app's primary strength lies in its integrated payment system that works directly at the pump. A key feature is 'Pay at the Pump,' which lets users select their pump number, apply any available fuel discounts from the rewards program, and complete the transaction entirely from their smartphone. This is particularly useful for avoiding lines inside or during off-hours. Users can also pre-purchase fuel credits or redeem points for discounts, which are automatically applied during the in-app payment flow. However, some user reviews indicate that the contactless 'tap to pay' function at the pump can occasionally fail, though the manual Pay at the Pump option within the app provides a reliable workaround. The app consolidates payment and rewards, meaning the discount is guaranteed and visible before authorizing the pump. For regular 7-Eleven customers, it effectively turns a routine gas stop into a more efficient, reward-earning transaction without the need for physical cards or cashier interaction.
