Extron ShareLink Pro

Extron ShareLink Pro is a free app for sending phone and tablet content to a room display through an Extron ShareLink Pro presentation system. It is a strong fit for equipped meeting rooms that need flexible presenter access, but a poor choice if you need screen sharing without dedicated Extron hardware.

Overview

ShareLink Pro handles images, video, and device screen content, with options for open participation or moderator-led sharing. Its central trade-off is clear: the app itself costs nothing, but its usefulness depends on a compatible ShareLink Pro system in the room.

Key features

A system can show up to four content sources at once, which helps groups compare materials or keep several presenters visible. That capacity suits many collaborative discussions, though rooms that need more than four simultaneous sources will need another approach.

Collaboration mode lets any user share; Moderator mode gives a designated person control over who can present. The first favors quick, informal contributions, while the second is better for orderly meetings. A Welcome Screen Display ID Code helps direct content to the intended display, and Extron says transmissions between devices and the system are encrypted.

The Android app connects over the existing Wi-Fi network. The system supports Apple and Android mobile devices as well as macOS and Windows computers. For organizations with multiple units, Extron GVE can manage setup, configuration, and firmware updates centrally. ConferenceShare is a related option for meetings: it shares video and audio from in-room USB devices with Windows or macOS laptops running Teams, Zoom, or other UC meetings.

Pricing

The ShareLink Pro app is free: its listed plan costs nothing and covers iPhone and iPad use. The plan requires an Extron ShareLink Pro presentation system, so the free price does not make it a standalone alternative to general-purpose screen-sharing apps. Extron says product pricing information is available to Extron Insider customers; no hardware price is stated here.

Platforms

The app's platforms are Android, iOS, macOS, web, and Windows. The free plan specifically covers iPhone and iPad and requires the Extron presentation system. Android connects through the existing Wi-Fi network; the system also supports Apple and Android mobile devices and macOS and Windows computers.

Who it's for

ShareLink Pro makes sense for meeting rooms already equipped with the Extron system, especially where groups need to share several sources or choose between unrestricted participation and moderator control. Organizations managing multiple units may also value centralized configuration and firmware updates. If you want a screen-sharing app that works without that room system, this is the wrong fit.

Pros and cons

• Pros: Up to four simultaneous sources support side-by-side comparison and multiple contributors.
• Pros: Collaboration and Moderator modes accommodate both open discussion and controlled turn-taking.
• Pros: Encrypted transfers, a display ID code, and centralized management address security and multi-unit administration.
• Cons: A ShareLink Pro presentation system is required, limiting the app to rooms with compatible hardware.
• Cons: Four simultaneous sources may not be enough for meetings that need a larger number of presenters on screen.

Alternatives

Screen Sharing Software is a useful starting point if you want to compare options beyond a room-system-dependent app.

• CrankWheel is worth considering if its free allowance of 15 meetings per month, three viewers per meeting, and one-week recording retention fits your sharing needs.
• AirDroid Cast offers a free same-WLAN casting plan with one simultaneous login; choose it if that setup fits better than requiring an Extron room system.
• Screenleap has a free plan capped at 40 minutes a day and eight viewers, making it an option for time-limited sharing without ShareLink Pro hardware.
• Deskreen has a free open-source Community plan for one connected device, a fit for readers who prioritize that model and device limit.
• LetsView offers free screen mirroring at SD resolution, with one connection, a 4M maximum bitrate, and 30fps maximum framerate.
• ViewSonic AirSync is another option in this category.
• Kramer VIA is another option in this category.
• Optoma Display Share is another free option in this category.

Verdict

Choose Extron ShareLink Pro if your room already has the required system and you want a free way to share multiple sources with a choice of open or moderator-controlled participation. Look elsewhere if you need a standalone tool, or if your meetings need more than four simultaneous content sources.
