Power Apps Mobile Preview

Test your in-development Power Apps mobile experiences on a real device — no rebuild, no resign, no store submission. Power Apps Mobile Preview is the developer companion app for the new React Native–based Power Apps mobile runtime: scan a QR code from your local Metro bundler (or paste a dev URL) and your app loads instantly on your phone or tablet, exactly the way it will run in production.

Think of it as the Power Apps equivalent of a dev sandbox — purpose-built for makers and engineers iterating on the next generation of Power Apps mobile.

WHAT'S INSIDE

Power Apps Mobile Preview is a thin host that loads your in-progress app bundles over the wire so you can see code, layout, and data changes in seconds.

• Scan-to-load: Point the in-app scanner at the QR code printed by your local Metro / Expo dev server and the JS bundle streams onto the device.

• Manual URL entry: Type or paste any reachable dev-server URL (e.g., http://192.168.1.20:8081) when QR scanning isn't an option — tunnels, remote machines, restricted networks.

• Fast Refresh: Save a file in your editor and watch the change appear on device, with component state preserved where possible.

• Native module parity: Bundled with the same native modules the production Power Apps client ships — auth, connectors, file system, camera, location, secure storage, telemetry — so what you test is what your users will get.

• Sign-in with your work or school account: Authenticate once with Microsoft Entra and your dev apps can call Dataverse, Microsoft Graph, and custom connectors with real tokens.

• Recent connections list: Quickly re-open previously loaded dev URLs without re-scanning.

• Diagnostic overlay: Surface bundle URL, runtime version, JS errors, and red-box stacks for fast triage.

WHO IT'S FOR

• Makers previewing custom React Native components and pages before publishing.

• ISVs and partners building native extensions against the Power Apps mobile runtime.

• Engineers on the Power Apps platform team validating SDK and connector changes end-to-end on real hardware.

TIPS

• Make sure your phone and dev machine are on the same Wi-Fi network — if they aren't, use a tunnel (e.g., expo start --tunnel) and paste the public URL.

• Shake the device (or use the menu) to reload the bundle, toggle the element inspector, or open the dev menu.

• Long-press a recent connection to remove it from the list.

• This app is for development only. Production apps should be installed via the regular Power Apps mobile app or your enterprise distribution channel.

PREVIEW DISCLAIMER

This is a preview release intended for development and evaluation. APIs, behaviors, and supported native modules may change before general availability. Do not rely on this app for production workloads.
