Some key features to consider when developing an educational app include engaging and interactive content, clear and concise instructions, customization options, progress tracking and assessment, accessibility, and compatibility with different devices, and integration with other platforms or tools. Additionally, it's important to consider user feedback and incorporate it into the app's ongoing educational app development services and updates to ensure it remains relevant and effective.
