# PoseTracker

> Human pose estimation SDK for React Native (Expo), iOS, Android and web. Free on-device MoveNet keypoints, optional API-key exercise engine.

Industry-leading motion tracking and human pose estimation for mobile apps, powered by TensorFlow's MoveNet — built by developers, for developers. Three integration paths: a native SDK for React Native (Expo), iOS, Android and the web with free on-device keypoints; a classic WebView/iframe API; and ready-made built-in tools (flexibility analysis, pose comparison). An optional API key unlocks rep counting, joint angles and a form score on top of the free keypoints. Studio on the homepage matches a natural-language request (for example count squats in a React Native app, measure jump height, or track a front-split angle) to an official catalog integration snippet. Custom movements continue in the PoseTracker app after sign-in. PoseTracker v2 (2026) is the current product: native SDK packages plus Studio-authored custom movements on the same on-device MoveNet engine.
