Calculadora is a free app for Android that lets you do basic calculations. With the calculator, you can easily calculate the price of a product or service, the interest you will earn on your savings, and the profit you will make on your business.

The app is very simple to use and lets you use multiple methods for calculating the price, including adding, subtracting, multiplying, and dividing. You can also use the calculator to calculate the area, volume, and weight of an object.
