Cross-Platform Language Learning App

I need an MVP language-learning application built simultaneously for iOS and Android. The core of this first release is a set of interactive lessons that guide users through reading, listening, and quick touch-based response activities.

Key requirements
• Single shared codebase (Flutter, React Native, or similar) so we can publish to both App Store and Google Play quickly.
• Clean onboarding, email / social login, and a simple dashboard that shows lesson progress.
• Lesson engine that supports text, images, and audio prompts with instant feedback to keep the user engaged.
• Basic local data caching and a lightweight API wrapper so I can plug in my own lesson content.
• Build and hand-over of all source code, project files, and store-ready binaries.

Timeline is urgent—I’d like a working prototype uploaded to TestFlight and an Android test track as soon as possible, with the complete hand-off right after that. If you have experience shipping interactive educational apps and can start immediately, let’s talk.
