About OBS Controller
Simple is better. This app is focused on having a simple mobile scene switcher in OBS. In OBS v28 and later it should work out of the box. For earlier versions, it requires the obs-websocket plugin to be installed. You can download it here: https://obsproject.com/forum/resources/obs-websocket-remote-control-obs-studio…
OBS Controller is listed on both the App Store and Google Play from Fallen Starlight AB, so you can install it on Android phones and tablets. The Play Store listing shows 10,000,000+ installs.
