행복1톤 is an Android application designed to streamline the LPG charging membership experience for users. This free app allows customers to manage their '행복충전 멤버십' efficiently, ensuring they can take full advantage of the benefits provided by SK가스. Users can easily collect their membership card at various SK가스 charging stations, register it within the app, and start earning points with every LPG refill by simply showing their card to the attendant.

The app also provides optional features such as location services for finding nearby charging stations, camera access for photo registration, and notification settings for updates on offers and benefits. While the essential permissions ensure the app's stability, users can choose to skip some optional permissions without affecting the core functionality of the app, although some features may be limited.
