The market for driving license exam preparation apps has many products, so initially I also wondered: “Should I add another app to the mix?”

The reason that made me determined to create one is the real experience of trying out many existing apps. The content is generally quite comprehensive, but the advertisements appear frequently, interrupting while studying or taking the exam, making the review process easily disrupted.

Therefore, I tried to build an application that is simpler:

• Review the set of 600 questions by chapter.
• Take practice tests based on the selected license class.
• Revisit incorrect answers and the 60 critical questions.
• Track learning progress and exam history.
• Lookup traffic signs, traffic laws, and penalties.
• Recognize traffic signs using the camera.
• Most content can be used offline.

My app also has advertisements to cover development costs, but I try to place ads in the least intrusive positions: not interrupting while answering questions, not taking up the full screen during exams, and not disrupting the review process.
