Education Website & Mobile App

I’m building a small-scale learning platform and need everything assembled into one seamless ecosystem. On the mobile side I want native apps for both iOS and Android that let students log in securely and browse/download their course materials right from their phones or tablets on payment of fees online.A clean, distraction-free UI and smooth offline reading will help keep engagement high.
Additionally I need live lectures from big blue button.
Basically we like to run a coaching academy.

For the web, the first milestone is a responsive site where new learners can complete their own student registration. Once registered, the same credentials must carry over to the apps so users have a single sign-on experience across all devices.

Core expectations
• Shared database or API layer so content and user data stay perfectly in sync.
• Admin console for me to upload, reorder and retire course files (PDF, video, audio).
• Basic analytics: number of sign-ups, daily active users and material download counts.
• Source code delivered in a private Git repository with clear setup instructions.

Acceptance criteria
1. User registers on the website, then logs into either app without re-entering details.
2. Course material opens and streams/downloads without errors on current iOS & Android versions.
3. No critical accessibility violations (WCAG AA minimum).
4. Live lectures got recorded on a dedicated server.

If you’ve shipped similar education products before and can prove it with a quick demo or store links, I’d love to review your approach and timeline.
