ДЭК Якутскэнергосбыт is a lifestyle app developed by Iserv for Android devices. This free app is designed to provide users with a convenient way to manage their utility bills. With this app, users can pay their bills, monitor their account balance, view their payment and billing history, and submit meter readings for electricity, hot and cold water supply. The app also enables users to add multiple accounts to their profile and generate receipts.

To get started, users need to install the app on their mobile device, register by providing their login credentials and email address, and log in to the app. They can then add one or more accounts to their profile by selecting their management company, address, and entering the date and amount of their last payment. Alternatively, users can pay their outstanding balance of any amount greater than 300 rubles, and their account will be automatically linked to the app.
