Develop an Android App for Educational Purpose

Points to be noted: - UI Design is already in process and is expected to complete soon (within 1-2 weeks). Same will be shared with you. - One of the most important features we require is smooth text-to-speech conversion. The user can opt to listen to question & answers. - App will have a walkthrough when it opens for the first time in any device. - It will have sign in/sign up with email, facebook, google. - It will have subjects, chapter inside those subjects and different types of questions in each chapter. Progress tracking will also be needed. - It will have in-app purchases i.e. to unlock full content user will have to pay or enter a unique code. - MVC Framework is recommended for the development.
