7. How to detect whether your canvas app is running in Power Apps Studio or Player

You can check whether your app is running in Studio (design mode) or Player (live app) using the Host object.

isAppInDesignMode = StartsWith(Host.Version, "PowerApps-Studio");

This returns true in Studio and false in Player.

Why it matters

• Show test or debug features only in Studio.
• Handle features differently for real users.
• Avoid errors by adding fallback options in Player.
