# Try on your phone

> Run PoseTracker in Expo Go in about 30 seconds — no Xcode, Android Studio, or API key.

See live pose estimation on your phone. Same three-line SDK as the [Quickstart](/quickstart).

## 1. Download Expo Go

[iOS App Store](https://apps.apple.com/app/expo-go/id982107779) · [Google Play](https://play.google.com/store/apps/details?id=host.exp.exponent)

## 2. Open a Snack and tap **Run on device**

Pick the package you want to try:

<Tabs>
  <Tab title="Offline">
    Bundled MoveNet — keypoints work without downloading the model.

    [Open the offline Snack](https://snack.expo.dev/@fsepret/posetracker-sdk-demo-app)

    Or scan this to open that Snack page, then tap **Run on device**:

    </Frame>
  </Tab>

  <Tab title="Light">
    Smaller install — needs network to load TF.js + MoveNet.

    [Open the light Snack](https://snack.expo.dev/@fsepret/posetracker-sdk-light-demo-app)

    Or scan this to open that Snack page, then tap **Run on device**:

    <Frame>
      <img src="https://mintcdn.com/posetracker/7KUtLzVStRLGJPP9/images/snack-light.png?fit=max&auto=format&n=7KUtLzVStRLGJPP9&q=85&s=135afa33d884c738d0ac5180e1a63d1a" alt="QR code for the PoseTracker light Expo Snack" width="220" data-path="images/snack-light.png" />
    </Frame>
  </Tab>
</Tabs>

## 3. Scan the QR code Expo shows

Expo Go opens the demo. Point the camera at yourself — skeleton overlay in a few seconds. No API key.

<Tip>
  The QR **on the Snack page** (after **Run on device**) is a live session. Use that one with Expo Go. The images above only open the Snack URL; they stay valid until the Snack is unpublished.
