We strongly suggest using the Streamlabs OBS app as your streaming software of choice - for mobile devices, you should be able to download it from your device's official app store.
Also note that, while you can use the Streamlabs OBS app to send the video/audio from your mobile device to our streaming servers, you'll still need a PC to access your Artist Panel and start and stop your stream.
Lastly, note that if the Streamlabs OBS app is not available in your official digital store, it might mean your device doesn't meet the necessary minimum requirements to run that app. In this situation, we suggest you instead use a PC or another device to stream to Sessions.
