I’m building a mobile learning experience that runs smoothly on both iOS and Android. The core of the app is a library of MCQs. Access to the content is gated by a simple email-and-password sign-up / sign-in flow. Any experience in developing social chat feature is a must for this project. To keep deliverables clear: • Fully functional iOS and Android builds compiled from the same codebase (Flutter, React Native or similar). • Rich-text viewer that supports at least basic formatting controls. • MCQ module that records a user’s chosen answer and reveals the correct one with an explanation. • Clean, intuitive UI that matches modern platform guidelines. • Source code, build instructions and a short hand-off document so I can publish updates in both stores without extra help. I’ll provide the question bank and note content; you wire everything up, test on real devices and hand over a polished release-ready app.
