The E.ON app is a comprehensive tool designed for iPhone users to manage their electricity and gas supplies effectively. It offers features such as monitoring active supplies, viewing bill history, and tracking the purchase of new appliances like boilers and air conditioners. Users can make secure payments via PayPal and Nexi, perform self-readings for gas, and adjust their energy consumption settings to optimize usage.

In addition to management features, the app promotes sustainability by allowing users to calculate their carbon footprint and engage in eco-friendly missions to earn ecoPoints. These points can be redeemed for green rewards or carbon credits. The app also provides updates on energy news, offers bonuses for bill discounts, and includes an accessibility commitment, ensuring a user-friendly experience for all.
