RegionMirror is an innovative macOS application designed to revolutionize screen sharing, especially for users with ultrawide monitors. It transforms any selected region of your display into a standard, shareable macOS window, ensuring your audience sees crisp, readable content in Zoom, Teams, Slack, or Discord, while you maintain your full desktop workspace and privacy. This tool is essential for professionals, developers, sales teams, trainers, and consultants who frequently present from large or ultrawide displays in virtual meetings, solving the common problem of unreadable, cramped screen shares.
Key Features
Share any custom screen region as a normal macOS window.
Optimized for ultrawide monitors, ensuring audience readability.
Seamlessly switch between multiple applications within the shared region.
Define presets for shared screen regions and switch between them on the fly.
Built-in annotation tools (arrows, text) for clear communication.
One-click privacy blur to hide sensitive information instantly.
Integrated whiteboard for collaborative brainstorming and sketching.
Customizable global keyboard shortcuts for instant sharing and region recall.

Use Cases
RegionMirror significantly enhances virtual presentations across various professions. Developers can effortlessly walk through code, terminal outputs, and documentation within a focused, readable frame, keeping their extensive IDE workspace private. Sales and demo teams can smoothly transition between product demonstrations, presentation slides, and browser content without interrupting the share, all while their personal notes remain off-screen. Trainers and consultants benefit from the ability to teach using multiple applications, annotate directly on the screen with arrows and text, and utilize a built-in whiteboard for complex explanations, ensuring dashboards and reports are presented clearly while sensitive client data can be blurred instantly.
Pricing Information
RegionMirror offers a freemium model. It is free to download, with all features unlocked for a 7-day or 10-sharing session trial. After the trial, sharing continues with a fixed 1080x720 region. A one-time in-app purchase of $19.99 unlocks custom region sizes, annotations, the privacy blur, and the whiteboard feature. There are no subscriptions or ads.
User Experience and Support
As a native Mac app, RegionMirror provides a smooth and intuitive user experience, appearing sharp on Retina displays and integrating seamlessly into your menu bar and Dock. It runs efficiently on both Apple silicon and Intel Macs (requiring macOS 13.5 or later). Setup is straightforward, requiring no drivers or plugins – simply download, select a region, and share the window.
