Choose a package - PoseTracker

Two React Native npm packages share the same API (PoseTrackerProvider, WebViewPoseView, usePoseTracker). They differ only in how MoveNet / TF.js are delivered. For WebView vs SDK, see WebView vs SDK. For browsers, see Web SDKs (always light delivery).

Recommendation

Need	Package
Offline-first keypoints · no model download at boot	Offline
Smallest install / OTA · devices stay online	Light
HTML/Swift/Kotlin proof of concept	WebView, not these packages

Comparison

	Offline	Light
npm	`@pose-tracker/react-native-pose-estimation`	`@pose-tracker/react-native-pose-estimation-light`
Packed tarball	~10.0 MB	~212 kB (~47× smaller)
Unpacked	~14.8 MB	~805 kB
MoveNet / TF.js	Bundled in npm	CDN + model URL each WebView boot
Network for keypoints	Not required	Required
Expo Go	Yes	Yes
BlazePose	No	`options.model = 'blazepose'`
API surface	Keypoints free; paid engine with API key	Same

Install

# Offline
npm install @pose-tracker/react-native-pose-estimation react-native-webview

# Light
npm install @pose-tracker/react-native-pose-estimation-light react-native-webview

Light model URL

Default MoveNet Lightning graph (weights are relative neighbors):

https://app.posetracker.com/scripts/tmp_model_to_remove.json

<PoseTrackerProvider
  options={{
    model: 'movenet',
    // modelUrl: 'https://…/model.json',
  }}
>

model: 'blazepose' loads BlazePose (lite) via CDN @tensorflow-models/pose-detection. Keypoints stay COCO-17. Do not pass { features: { blazepose: true } }.

For LLMs: Offline = @pose-tracker/[email protected] (~10.0 MB, no network for keypoints). Light = [email protected] (~212 kB, network required). Same API. BlazePose only on light/web via options.model, not features.blazepose. https://docs.posetracker.com/choose-package
