I want an iPhone app that acts like a personal yoga coach at home. Using the front camera, it should track my pose in real time, compare my joint positions to expert references for each posture, and speak corrections like “straighten your back” or “knee over ankle.” After a flow, I want a per‑pose accuracy summary saved to my account. I prefer Objective‑C with an MVC structure. Use UIKit for browsing/selecting classes, and layer a SwiftUI overlay on the live camera preview for guidance. Any required ML/pose detection libraries can be added via CocoaPods.
