vCastSender

Share to a ViewSonic display

vCastSender is for sending content from an Android device to a ViewSonic ViewBoard interactive flat panel. It suits teachers, presenters and meeting participants who need to show a phone screen, photos, videos, music, documents or camera footage on a shared display. The app also supports annotations and live recording streams as part of the ViewBoard Cast setup.

A companion, not a general casting tool

This app is designed to work with ViewBoard’s vCastReceiver software. Your device and the panel need to be on the same network; you then connect through the receiver using its PIN. The purpose is specific: presenting and collaborating through compatible ViewSonic displays. If you need a general-purpose way to cast to a range of televisions, this listing does not establish that vCastSender is the right fit.

Controls and permissions

Alongside sharing content, vCastSender provides annotation tools and can let you control the displayed content from your device. It also offers “Reversed Device Control,” which allows the designated display to operate your phone or tablet. That feature uses Android’s Accessibility Service API, and the app requests storage access for file sharing. These permissions are relevant to its functions, but worth considering if you only want to mirror a screen.

ViewSonic says the accessibility service is used only for reversed device control and that the app does not collect personal or device information or monitor your operations. Check the permission prompts and decide whether those controls match how you plan to use the app.

Who it is for

vCastSender has 100,000+ installs and a rating of 2.84 from 324 ratings. Those figures suggest it has a real user base, but they do not change its main limitation: its usefulness depends on having a compatible ViewBoard and receiver available. For a ViewBoard classroom or meeting room, its focused set of sharing and control tools may be relevant; without that setup, there is little reason to choose it.
