# PoseTracker React Native SDK

> PoseTracker React Native SDKs — human pose estimation for iOS and Android in seconds. Offline and light packages, free keypoints, optional exercise engine.

**PoseTracker** is a React Native human pose estimation SDK for **iOS and Android** (including **Expo Go**). It runs **MoveNet SinglePose Lightning** (17 COCO keypoints) in a WebView, streams **free keypoints without an API key**, and unlocks exercise intelligence (reps, form score, jumps) with an optional API key.
