Interactive 3D Anatomy App

I want to bring a fully interactive 3D skeleton to iOS and Android so users can spin, zoom, and tap any bone or muscle for instant, targeted information. When a body part is selected the app should present three clear paths:

• Medical terminology and clinically accurate details about the structure.
• A concise AI-generated summary of common pain sources in that region.
• Evidence-based strengthening or stretching guidance — shown through either realtime 3D animations or smooth video playback, whichever best suits the workflow you recommend.

The browsing experience needs to feel effortless: touch-driven selection, optional search, and a minimal UI that never hides the model. I’m open to Unity, Unreal Engine, or a robust native 3D framework as long as performance on recent iOS and Android devices stays above 60 fps.

For this first milestone I’m looking for:
1. A working skeleton prototype with accurate muscle overlays.
2. Tap-to-info panels populated with placeholder text pulled from a simple JSON or lightweight backend.
3. One sample exercise and stretch presented in your chosen 3D or video format so we can validate the media pipeline.

Code must be clean, documented, and ready for later integration with external health-service APIs. If this sounds like your specialty, tell me how you would handle the real-time rendering, content management, and cross-platform deployment, and include links to any similar visual-or medical-centric apps you’ve shipped.
