حاسبة كهرباء روناكي is a utility app designed for Android that helps users estimate their monthly electricity consumption. By allowing users to input various electrical appliances and their daily usage hours, the app calculates total energy consumption in kilowatt-hours (kWh). It is particularly useful for individuals looking to understand their electricity usage without needing an internet connection.

The app categorizes consumption into different types such as residential, commercial, industrial, and agricultural. Users can select devices from a predefined list and specify the daily operating hours to obtain an estimated consumption cost. While the app provides a guideline for electricity usage, it is important to note that the results may vary from official bills due to fluctuating electricity prices and device efficiency.
