Simulador OAB is an Android application designed by Mauricio Copetti. It is a free app that falls under the Education and Reference category. The app has three main features that cater to the needs of law students preparing for the OAB (Ordem dos Advogados Brasileiros) exam.

The first feature is the simulated test for the first phase of the OAB exam. The test is almost identical to the actual exam, and users have 5 hours to complete it. After completing the test, the app displays the result.

The second feature is the study module, where users can check the correct answer after selecting an alternative. There is no time limit in this module, and users can learn at their own pace.

The third feature is the history of simulated tests, where users can track their progress and see how they are performing in terms of time and questions.

The app has an attractive design and is easy to use, making it an ideal choice for law students preparing for the OAB exam. However, it is important to note that this app only provides a simulated test, and its use alone may not be sufficient for passing the actual exam.

Overall, Simulador OAB is a comprehensive app that provides law students with an effective tool to prepare for the OAB exam.
