AI Fitness Challenge Platform

Fitness app using live camera detection to count push-ups and enable multiplayer challenges.

Problem

Users wanted accurate rep counting and social motivation without wearable hardware.

On-device Vision framework for pose estimation and rep counting, with Firebase for real-time leaderboards and challenges.

Camera feed is processed on-device with Vision and Core ML. Counts and challenge state sync via Firestore with optimistic updates.

SwiftUI views for camera and overlays; Firebase Auth and Firestore for users and challenge data.

Maintaining high accuracy across lighting and angles while keeping battery usage acceptable.

Automated workout tracking with real-time engagement.
