Teoriakoe (B-license) is an educational app available on the Android platform. Developed by dNT, this app is designed to help users prepare for the theory test for a private car license in Finland. With its format mirroring the real theory test, Teoriakoe consists of 50 picture questions and 10 text questions. To pass, users must have no more than 8 errors among the image questions and 3 errors among the text questions.

The app offers a comprehensive selection of over 230 picture questions and over 30 text questions, which are randomly selected each time you practice. This ensures that users get a varied and challenging experience during their preparation. Teoriakoe is not only suitable for those who are currently studying for their car license, but also for those who already have a driving license and wish to improve their road skills. The app is available in Finnish, Swedish, and English, making it accessible to a wide range of users.
