Flitz Shell

About this app

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.
