E-Soru is an Android application developed by Unitinia that allows users to take a picture of a question they are struggling with and upload it to the app. Within a short amount of time, the solution to the question will be sent to the user's phone in either video or visual format completely free of charge. Users can also earn points by helping to solve other users' questions.

The app has a 24/7 support center that users can contact if they encounter any issues. E-Soru is completely free and the aim of the developers is to provide support to students, not to make money. Users can also rest assured that all uploaded questions and solutions are monitored to ensure that they are relevant and appropriate. In the future, the app will also feature free coaching, question tracking, topic measurement, and scheduled study tools.

Overall, E-Soru is a great app for students who need help with their studies. It's easy to use, completely free, and offers a wide range of features that will help users to improve their knowledge and skills.
