Cart Calculator is a free and easy-to-use shopping cart manager and calculator app, available for Android. The app is designed to make your shopping experience simpler and more objective, unlike other grocery list managers. With Cart Calculator, you can manage your shopping cart by adding products and increasing or decreasing their quantities. The app displays the total due of the products in your cart based on their prices and quantities, so you can always be aware of how much you're spending even before reaching the checkout. This feature is especially useful when you're on a budget or have little money.

Cart Calculator is straightforward and generic, which means you can use it outside the grocery store or market, such as in pubs, restaurants, or movies. Plus, it is a free, open-source software distributed under the GNU General Public License version 3, meaning anyone can access its source code, study it, or modify it for their own needs. Overall, Cart Calculator is a great app for those looking for a simple and effective shopping assistant.
