ExcelsiorCreative/yoga-therapy-app ? reverse-engineered prompt

Build me a yoga therapy mobile app in React Native with Expo that helps people choose yoga poses based on common physical and mental health concerns, then guides them through each routine with simple voice cues, timers, a prep countdown, and the ability to pause or skip steps. I want a clean wellness style app with Home, Progress, and Settings tabs, plus features like favorite poses, custom routines, practice history, streaks, weekly minutes, reminders, and a special Surya Namaskar flow with breathing guidance.

Also include a camera based live pose corrector that can look at the user while they practice and speak helpful corrections out loud. It should work through a backend service so the app can run offline for the regular features, and only use the internet for the live pose checker. If you need to, look up the current Expo and FastAPI docs online to make sure the setup is solid and the app builds cleanly.
