Calculadora de Energia is an Android app developed by pwa smart. It is a free utility tool that enables users to calculate their energy consumption and cost. The app uses data from Aneel to determine the average price of kWh (kilowatt-hour) in the user's state. With this information, the app calculates the energy consumption based on the equipment's power and displays the cost in R$.

The app has two main features. First, users can perform quick calculations on the consumption and cost of a single device. Second, they can create a consumption profile to predict their monthly electricity bill. The app also provides suggestions for energy-saving and conscious use of electricity, aiding users in reducing their energy consumption and bills.

The app is a smart solution to track energy consumption and is suitable for anyone looking to save on their electricity bills or reduce their carbon footprint.
