Power Apps Mobile Preview vs ChairBack

Test your in-development Power Apps mobile experiences on a real device — no rebuild, no resign, no store submission. Power Apps Mobile Preview app is a 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. 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. • Mobile Preview app is for development only. You will need to package and distribute your own production apps to App Store or enterprise distribution channel. DISCLAIMER This is a developer only release intended for development and evaluation. APIs, behaviors, and supported native modules may change before general availability. Do not rely on Mobile Preview app for production workloads.

ChairBack is the app for the chair - for the barber running it, and the client sitting in it. If you cut hair, your whole book lives on your phone. See your day hour by hour or your month at a glance, and take a booking, move one, or block off time in a couple of taps. When the cut is done, check your client out right there at the chair and record what you actually collected, whether that was cash, card, or transfer. A walk-in takes one tap: no name, no signup, just what they paid. Between clients you can see who is coming in next, who has not been back in a while, how full your chair really is, and what your time is honestly worth. Already booked somewhere else? Bring your book with you from Acuity or Square, or import a client list, and keep the appointments you already have. If you are the one in the chair, there is nothing to sign up for. Find your shop by its exact name, or open the link your barber sent you, and your rewards card is waiting - your visits, the tier you are on, and how close the next one is. Book your next cut in a few taps, or set a standing appointment so your usual time stays yours for the weeks ahead. A reminder lands before you are due so you never lose the slot, and your card can live in Apple Wallet instead of your back pocket. Barbers, stylists, and anyone else who works a chair will find their own words in here rather than someone else's. And if you keep a chair of your own, you can flip between the dashboard and your own rewards card without signing out. Sign in with Apple or Google, or with the email you already use. ChairBack takes 0% of what you charge. Card processing is handled by our payment processor, whose own fees apply. Your client list is yours, and you can export it whenever you like. Just looking? There is a demo on both sides, so you can walk through the whole thing first.
