ZoneShare mirrors selected screen areas to separate, resizable windows optimized for video conference sharing. The app addresses a common ultrawide monitor problem: full-screen sharing makes content appear as a tiny, unreadable strip for viewers, while partial sharing wastes space on empty areas.
The workflow is straightforward: ZoneShare lives in the menu bar and activates with customizable hotkeys. Users select the screen area to mirror, and ZoneShare creates a separate window showing that content in real-time. The mirrored window can be resized to standard aspect ratios like 16:9 or 4:3 for optimal video conferencing display.
A focus overlay darkens everything outside the selection during area selection, making it clear what the audience will see. Privacy controls can blur sensitive content in the background. The mirrored window updates instantly with no noticeable lag, using approximately 3-5% CPU during active mirroring.
ZoneShare works with all major video conferencing platforms including Zoom, Microsoft Teams, Google Meet, and Webex. Users share the ZoneShare window instead of the entire screen for precise content delivery.
Requirements include macOS 13 Ventura or later with native support for both Intel and Apple Silicon Macs. Developer Lunara Apps built the app for professionals who regularly present or share screens.
ZoneShare costs $9.99 as a one-time purchase from the App Store. The app has earned a 4.8/5 star rating.
Limitations: The app addresses a specific use case. Users with standard aspect ratio monitors may not encounter the ultrawide sharing problem that ZoneShare solves. Setup requires briefly exiting the presentation flow to select mirror areas.
Alternatives include macOS native window sharing, though this lacks the flexible area selection and aspect ratio adjustment.
Suitable for users with ultrawide monitors who regularly share screen content during video calls, particularly developers doing code reviews and designers presenting mockups.
