Enem 2023 Simulados is an Android application developed by RALL that aims to help students prepare for the National High School Exam. The app offers simulated tests for the exams of the years 2017, 2018, 2019, 2020, and 2021, allowing students to test their knowledge and get ready for the upcoming exam.

One of the app's main features is that the tests are fully offline, which means that students don't need an internet connection to use them. The app also offers random questions from the selected subjects, a history of hits and misses, and the ability to check the result of each question without having to complete the entire test. Additionally, the app offers a dark mode and the option to adjust the text's type and size for better readability.
