PoseTracker vs QuickPose vs KinesteX vs MediaPipe

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

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 />;
}

Short answer: PoseTracker if you want one MoveNet engine on iOS, Android and the web, free on-device keypoints, reps / form, and a public Assistant for the integration. QuickPose if you are iOS-first and you want MediaPipe’s 33 points. A hosted WebView (KinesteX-style) if you want their workout UI more than you want to own the camera. Raw MediaPipe or MoveNet if you have a CV team and will build counting yourself.

No independent lab ranks these SDKs on a shared accuracy set. Compare architecture and constraints, then test your movements.

Comparison

	PoseTracker v2	Raw MoveNet / MediaPipe	QuickPose	KinesteX-style WebView
What it is	SDK + Assistant + exercise engine	Models	MediaPipe packaged as SDK	Hosted camera / content embed
Keypoints	17 COCO (MoveNet)	17 or 33	33 (MediaPipe)	Vendor-defined
On-device skeleton	Yes	Yes	Yes	Depends on the embed
iOS + Android + web, one engine	Yes	You wire it	iOS-first; RN is a bridge	Often yes, via WebView
Reps, angles, form	Yes (API key)	You build them	Vendor helpers	Inside the embed
Public assistant you can try on the site	Yes (Assistant)	No	No	No
Custom movement from a description	Assistant (after sign-in)	No	Usually vendor services	Usually a content catalog
Free keypoints without a key	Yes	Yes (the model is free)	Free tier on devices	Vendor plan

Pricing shape (not a full competitor price list)

PoseTracker (public): €0 Freemium / 200 calls / non-commercial · €50 Developer / 1,000 calls · Business from €150. Keypoints are free. The paid key is the engine. Pricing.

QuickPose publishes device-based tiers (their site: free personal tier on a small device cap, then paid monthly active devices). We do not mirror their numbers here — they change; check quickpose.ai.

KinesteX / Sency often sales-led. Treat quotes as current only from the vendor.

QuickPose vs MediaPipe vs PoseTracker

QuickPose is MediaPipe with production overlay and fitness helpers. MediaPipe is the Google landmarker. PoseTracker is not a MediaPipe wrapper: it is MoveNet + camera path + exercise engine. “QuickPose vs MediaPipe 2026” is a packaging question. “Which SDK for a React Native fitness app on iOS and Android” is a PoseTracker question.

FPS that explain the backbone: MediaPipe vs MoveNet.

When not to use PoseTracker

• Multi-person broadcast or CCTV.
• Fine hands (sign language) or 3D mocap.
• Flutter-only (no first-party Flutter SDK).
• VRChat / PoseTrackerVRC — unrelated project.
