Subscription Music Learning App

I am building a cross-platform music learning application and need a seasoned mobile developer who can take it from concept to App Store and Google Play launch. The heart of the product is a multi-audio player that streams (no local download) and offers rock-solid playback controls—play, pause and stop must feel instant and glitch-free even on low-end devices. Smooth buffering, background audio, and graceful interruption handling are essential.

Around that player, we’ll layer three distinct account types—Students, Teachers and Admins—each seeing only the tools they need. Students subscribe (monthly, quarterly, yearly plans), browse lessons, and record their own performances directly in the app to submit for feedback. Teachers will be able to review those recordings, add time-stamped comments, and mark assignments complete. The Admin portal should let me manage users, content, and subscription packages without touching code.

I value clean, intuitive UI/UX; please bring Figma or similar design chops alongside native or React Native/Flutter development skills. If you have launched subscription-based apps that integrate Apple/Google in-app purchases and handle server-side receipt validation, that experience will help us move fast.

When you reply, include links to at least two live apps that showcase:
• streaming or multi-track playback,
• in-app purchase subscriptions,
• and a thoughtfully designed learning flow.

I’m ready to start once the scope, timeline, and milestones are clear. Let’s create a practice tool musicians genuinely love.
