Cálculo de Frete Autônomo is a free Android app developed by C2 Comunicação. It is a comprehensive freight calculation app that takes into account everyday metrics, including fuel costs, vehicle maintenance, taxes, drivers, and helpers. The app offers four different types of calculations: Simple and Advanced Calculation, and Simple and Advanced Evaluation.

The Simple Calculation uses standard parameters, where you only need to provide data about the route, load, and loading, travel, and unloading time. Based on this, the app calculates how much you will spend and the profit margin you desire. The Advanced Calculation is more detailed and allows you to fill in the parameters completely to get a more accurate calculation.

Similarly, the Simple and Advanced Evaluation modes are for evaluating an existing freight offer. The Simple mode uses standard parameters, while the Advanced mode allows you to provide more details for a more precise calculation.

The app's calculation base was created by engineers working in the field, and the calculation values are constantly updated. The app aims to help users avoid losses and know how much to charge. The only thing the developers ask for is a good review if you like the app.

Note that the developers are currently working on a new version of the app to adapt to the new legislation that will soon come into effect.
