World Tracking on iOS (AppClip)

Why a bridge

Safari on iOS does not implement full WebXR. To offer World Tracking on iOS, Monolook uses a native bridge based on AppClip that:

• Runs native iOS tracking (ARKit) with direct camera access
• Exposes a WebXR-equivalent API to maintain code homogeneity
• Transfers position and orientation data to the web environment in real time
• Manages the complete XR session lifecycle on iOS

How it works

[User opens the experience in Safari]
        ↓
[Platform detection → iOS]
        ↓
[AppClip is launched]
        ↓
[AppClip activates native ARKit]
        ↓
[Bridge exposes WebXR-like API]
        ↓
[Your Vue/Three.js code works the same]

Platform detection

Use Bowser (or navigator.userAgent) to detect the platform and redirect to the appropriate flow:

import Bowser from 'bowser'

const browser = Bowser.getParser(navigator.userAgent)
const platform = browser.getOSName() // 'iOS', 'Android', etc.

Depending on the platform, the experience redirects to the appropriate flow (WebXR or AppClip).

Future compatibility

The SDK incorporates internal pose recalculation to maintain independence from the XR provider. If Apple implements full WebXR in Safari, the SDK can migrate automatically without changes to client code.

Integration

To integrate World Tracking on iOS you need the Monolook App/App Clip bridge and a World license. Request access in Get access.
