مادة تاريخ الأردن App is an Android application developed by One app 21 and falls under the Education & Reference category. The app offers over 900 questions that students can use to test their knowledge and review their material. The benefits of the app for students include self-testing, material review, the ability to select multiple units for testing at the same time, and the ability to choose the number of questions to answer, ranging from 5 to 971.

Once the student selects the number of questions and units they want to test or review, the app randomly mixes the questions and displays the first question on the screen. After the student answers, the app corrects the answer and moves on to the next question, continuing in this way until the last question is answered. At that point, the student's score for the entire test is displayed. The app is free to use and can be a useful tool for students preparing for the Tawjihi exams in Jordan.
