Flitz Shell lets Flutter developers share a work-in-progress build with their team and run it on a real device in seconds. You're in the middle of building a Flutter app and want a teammate to look at it before it's finished. Instead of a screen recording or rebuilding on their machine, share a link to the current build. Your teammate opens it in Flitz Shell and sees it running on their own device — the real app, with real gestures and real performance. WHAT YOUR TEAM CAN DO • A designer checks that an animation or transition feels right on a physical device. • A product owner walks through a new form or flow and gives feedback. • A QA engineer reproduces a bug on their exact device. • Another developer reviews your branch without pulling and building it. HOW IT WORKS • Build your Flutter app and serve the current build behind a link. • Share the link — it doubles as a QR code. • A teammate scans it with Flitz Shell. • Your in-progress app launches and runs at full native speed on their device. WHY TEAMS USE IT • Faster feedback — a teammate sees your change on a real device in seconds. • Real hardware — gestures, scrolling, fonts, and performance a simulator or a video can't show. • Stay in flow — show someone a change without interrupting your own work. • Clear diagnostics — if a build isn't compatible, Flitz Shell tells you exactly why. WHAT YOU NEED Flitz Shell is for Flutter developers and their teammates. The developer builds the app; anyone on the team opens a shared build on their device to review it during development. Flitz Shell is for reviewing your team's own work-in-progress apps during development. It is not an app store and does not deliver finished apps to end users. Learn more at https://flitz.dev
