How to use your old tablet to build a live streaming setup

Elgato’s Stream Deck Mobile app can turn an older iPad or Android tablet into a controller for livestreaming and other computer tasks. It offers a way to reuse a device that might otherwise sit unused, with buttons for actions such as muting a microphone, switching cameras or opening apps.

To set it up, install the app on a Windows 10 or later PC or a Mac running macOS 10.15 or later, and on a tablet running at least iPadOS 15 or Android 9. Pair them using a QR code; both usually need to be on the same local network, though Mac and iPad can connect by USB. The free version provides six buttons, while a Pro subscription raises the limit to 64 and costs $2.99 a month, $24.99 a year or $49.99 for a lifetime licence.
