From install to live keypoints

React Native and Expo Go. Keypoints stream on-device and need no API key.

1 — Install

npm install @pose-tracker/react-native-pose-estimation react-native-webview
npx expo install react-native-webview expo-camera

2 — Read the keypoints

import {
  PoseTrackerProvider,
  WebViewPoseView,
  usePoseTracker,
} from '@pose-tracker/react-native-pose-estimation';

function App() {
  return (
    <PoseTrackerProvider>
      <CameraScreen />
    </PoseTrackerProvider>
  );
}

function CameraScreen() {
  usePoseTracker({
    onKeypoints: (e) => {
      console.log(e.keypoints.length, e.score);
    },
  });
  return (
    <WebViewPoseView
      style={{ flex: 1 }}
      drawSkeleton

    />
  );

Frequently asked questions

Pose estimation for mobile and web apps, answered.

What is the best pose estimation model for real-time fitness on mobile in 2026?

For a single person, in real time, on mobile and across platforms, MoveNet is the common default: in the browser it holds about 34 FPS on a Pixel 5 and 51 on an iPhone 12, where BlazePose sits around 11-12. PoseTracker runs MoveNet on-device on iOS, Android and the web, and adds rep counting, joint angles and a form score on top. See the 2026 model guide →

MediaPipe vs MoveNet vs BlazePose — which should I use?

MoveNet (17 keypoints) is lighter and faster for real-time, cross-platform mobile. MediaPipe / BlazePose (33 landmarks, 3D) is richer but heavier, better when you need 3D or hand and foot detail. PoseTracker is built on MoveNet and handles the camera pipeline and the business layer (reps, angles, form score) for you.

How do I add real-time pose estimation to a React Native or Expo app?

Install the PoseTracker SDK (@pose-tracker/react-native-pose-estimation), wrap your screen in the provider, and read keypoints from the hook. Keypoints are free and run on-device; an optional API key unlocks exercises. It works in Expo Go on iOS and Android. React Native guide →

Can pose estimation run in a web app or the browser?

Yes. The PoseTracker web SDK runs MoveNet in the browser over TensorFlow.js, with free on-device keypoints, from a script tag, an ESM import or a React wrapper. Web guide →

Does it work offline, and on both Android and iOS?

Yes. The offline React Native package bundles the MoveNet model on the device, so inference needs no network; the light package fetches the model at runtime. Both target iOS, Android and the web from a single integration.

Do pose estimation models give rep counting and form feedback out of the box?

No. Every model returns only keypoints and confidence scores. Rep counting, joint angles, a form score and comparison to a reference movement are a business layer you build yourself — or get ready-made from PoseTracker via an optional API key.
