The app mentioned in the text allows users to conveniently manage their online accounts for various services. Users can register or log into their accounts and use fingerprint recognition for secure and quick login. The app also allows users to easily switch between different accounts or properties. Users can check their account balance, payment and tariff details, view bills and payment history, and receive notification alerts and reminders. They can also make instant payments, submit meter readings, view messages and documents sent by the service provider, and renew or change their tariff. Additionally, users can refer a friend using a unique link and access FAQs or send messages for quick help.

For users with smart meters, the app provides additional features through the Energy Hub. Users can see how much energy they have used and the associated costs. They can also get an energy breakdown for specific activities like heating and cooking. The app offers personalized tips to help users save energy and money.

For users with smart meters on a pay-as-you-go plan, the app allows them to check their balance and top up their meters. They can set up auto top-ups or receive low-balance alerts. The app also provides a view of the top-up history.

However, the app is not compatible with traditional prepayment meters that do not allow online top-ups. Users with such meters can still manage other aspects of their accounts online by logging into or signing up for MyAccount.
