A quick camera check before the call starts
Preen keeps a live camera preview close at hand, so framing and camera selection take a moment instead of interrupting a meeting.
Preen is a small menu-bar camera preview for the moments just before a call. Open it to check framing, switch cameras, or mirror the image without opening a meeting app.
Keep the check lightweight
The preview is designed to stay out of the way when you do not need it and be ready when you do. During the trial, Preen also includes snapshot capture, microphone mute, and a floating window.
The app is available as a direct download. Free and safety features may remain available after the trial; a license for Preen unlocks paid features.
