Building an app like Khan Academy requires careful planning and execution. Start by defining your app’s goals, target audience, and core features like video lessons, quizzes, and progress tracking. Next, choose a tech stack that supports scalability and high-quality content delivery. Focus on intuitive UI/UX design to ensure ease of use. Develop and integrate secure payment options if offering paid courses. Testing and feedback are crucial to refine the app’s performance and user engagement. Finally, launch and continuously update your app to meet user needs and stay ahead in the competitive eLearning space.
