TRY OUR DEMO TOOLPoseTracker's real-time pose comparison analysis showing side-by-side golf stance measurement: reference posture with skeletal tracking (left) compared to user's current position (right) achieving 65% similarity score

Try it in 5 minutes

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

Install

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

Show the keypoints

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

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

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

Free tier: 200 API calls/month for reps, angles and form score.

Embed the comparison

WebView URL from the docs. Pose comparison uses reference=REFERENCE_UUID, the id you create in the dashboard. Do not add exercise on the same URL.

About the tool

Pose comparison puts a stored stance next to the person in the camera. You save a reference position. The live frame is matched to that reference, and the screen shows a similarity percentage.

The image on this page is a golf stance. The overlay reads 65 percent on that frame. That number is the label in the screenshot. It is not a lab result, and it is not a score the tool promises on every swing.

The match is between one person and one reference. PoseTracker’s pose engine is single-person, 17 COCO keypoints, on the device. Two athletes in the same frame, or a broadcast camera on a team, is a different problem. Fine hand or foot detail is also outside a 17-point skeleton.

Sports training, physical therapy and fitness apps use the score as feedback against a stance they chose: a yoga shape, a rehab position, a golf address. The score says the live skeleton is close to that reference. It does not diagnose, and it does not decide that a repetition counts. Counting and a form score are the exercise engine, behind an API key. The comparison demo itself is the public page at the button above.

The integration price printed on this page is a €4,000 setup fee and a subscription from €50 a month. That quote is for putting this comparison into a product. It is separate from the self-serve Developer plan, €50 a month for up to 1,000 API calls, listed on the homepage.

Frequently asked questions

What does the similarity score compare?

A stored reference stance and the pose in the live camera. The screen shows how close the two skeletons are, as a percentage. The golf image on this page is one demo frame labeled 65 percent. That label is the screenshot, not a published accuracy study.

Can I save my own reference?

Yes. You create a reference position and compare later camera frames to it. The reference is a pose you store, not a catalog the tool invents for you.

Does comparison need two people in the frame?

No. One person is compared with a stored reference. The pose engine used by PoseTracker is single-person. A crowd or a team-sport broadcast is outside this tool.

Is a high score a medical clearance?

No. The score says the live skeleton is close to the reference you stored. It does not diagnose, and it does not say an exercise is safe. The app that shows the score remains responsible for any clinical use.
