Find the cheapest price between 2 products with different quantities and values ​​in a supermarket. Example: 2.5L Coca-Cola for R$ 8.19 and 1L for R$ 4.59 which would you buy, which is cheaper? Hard to know right, without doing the math, that's why I developed the app to help you know which is the cheapest. You enter the ml or grams of the 2 products and the 2 prices then click on Calculate and the MaisBarato App already informs you which is the cheapest, you also have the option of putting the name of the products. There is a button to clear the fields, another is I teach you, fill in the fields so the user knows how it works. Simple and lightweight application, easy to use even for older people. The buttons are in simple text and easy to understand. Even the exit button has been put in, as I see some seniors struggling to exit apps. Happy shopping, with savings!!!
