You can live stream your phone screen to Twitch with a face cam using DemoScope (HD Face Cam Screen Recorder on the App Store and Google Play): open Stream mode, choose the Other App source, paste your Twitch stream key, and go live. Your screen broadcasts with a floating camera bubble sitting on top of it, and no computer or capture card is involved.
Short answer: To live stream your phone screen to Twitch with a face cam, use DemoScope’s Stream mode with the Other App source on iPhone, iPad or Android. Pick Twitch as the platform, paste your stream key from the Twitch Creator Dashboard, set bitrate, and tap start. A floating face cam overlays everything you broadcast.

What DemoScope’s Stream mode actually sends to Twitch
DemoScope’s Stream mode is a built-in RTMP/RTMPS broadcaster. It works by taking what DemoScope is capturing, compositing your front or back camera on top of it as a picture-in-picture bubble, and pushing that single video stream to Twitch, YouTube Live, Facebook Live, or any custom RTMP server.
There are two things it can broadcast, and the difference matters:
- In-app sources: a website, a photo, or a video from your camera roll. Face cam, touch indicators and top/bottom text overlays are all part of the stream.
- Other App source: your actual phone screen, across every app. DemoScope drops to the background, a system-wide floating face cam window stays on top, and your whole screen goes out live.
If your goal is “live stream my phone screen to Twitch with a face cam,” the Other App source is the one you want.
Steps to go live on Twitch from your phone
- Open Twitch on the web or in the Twitch app and go to the Creator Dashboard. Copy your primary stream key.
- Open DemoScope and switch to Stream mode.
- Select Other App as the recording source so the stream covers your whole phone instead of only in-app content.
- Choose Twitch as the platform and paste the stream key.
- Set your video bitrate (2500, 4500, 6000 or 8000 kbps) and audio bitrate (96, 128 or 160 kbps). Frame rate is 30 fps.
- Position the face cam bubble: drag it to a corner, pinch to resize, and pick circle, square, vertical rectangle or horizontal rectangle. You can also flip between front and back camera.
- Tap start. DemoScope sends itself to the background, the floating face cam stays on screen, and you navigate to the game, app or settings panel you want to show.
- Stop the stream from the system recording UI (iPhone) or the floating control panel (Android).
Spec line: DemoScope streams at 30 fps, 2500 to 8000 kbps video, 96 to 160 kbps audio, to Twitch, YouTube Live, Facebook Live or a custom RTMP/RTMPS URL.
On home Wi-Fi, 4500 kbps is the setting I reach for. 8000 kbps looks great on a fast upload and falls apart the moment you walk to the other side of the house.
The free route, and where it stops
The iOS built-in screen recorder and Android’s built-in recorder both save MP4 files to your device. Neither one speaks RTMP, so neither can push anything to Twitch, and neither composites a face cam over your screen. The Twitch mobile app itself is built around camera streams rather than broadcasting your phone’s screen. That leaves the built-in route fine for capture and useless for live screen broadcasting with a face on top.
If you want the longer comparison of capture tools, the ios screen recorder guide: built-in tool vs dedicated apps and iphone built-in screen recorder vs third-party apps both cover where the system recorder runs out of road.
DemoScope vs the built-in recorder vs Streamlabs Mobile
| DemoScope | iOS / Android built-in recorder | Streamlabs Mobile | |
|---|---|---|---|
| Streams to Twitch via RTMP | Yes | No | Yes |
| Face cam overlaid on your screen | Yes, draggable and resizable | No | Camera overlay supported |
| Broadcasts other apps and games | Yes, Other App source | No | Yes |
| Pricing model | Free with watermark, Pro $19.99 one-time | Free with the OS | Free tier plus paid subscription tiers |
| Free-tier stream limit | 10 minutes per stream, watermark | No streaming at all | Varies by plan |
| Multistreaming to several platforms | No | No | Available on paid tiers |
My position: if you stream from a phone occasionally and hate subscriptions, DemoScope’s $19.99 one-time Pro unlock is the better math. If you multistream to three platforms every night and need chat alerts on screen, DemoScope is the wrong tool and a subscription streaming app is the right one.
Honest limits before you go live
- No multistreaming. One RTMP destination per stream.
- No chat overlay. Twitch chat does not render into the broadcast. Keep a tablet or second device nearby.
- On iPhone, Other App streaming has no touch indicators and no teleprompter. Those are in-app recording tools only, because of how the iOS Broadcast Extension works. Tools over other apps are limited to Camera, PiP Border and Text on screen.
- On Android, you get more. The floating control panel stays over the other app with record/pause/mic mute, plus teleprompter, drawing, text and a laser pointer. Touch dots over other apps come from Android’s own “Show taps” developer setting, which DemoScope points you to.
- Free tier caps streams at 10 minutes and adds a watermark. Pro at $19.99 one-time removes both.
- No editing, captions or cloud hosting. DemoScope records and streams. Recordings land in your camera roll as MP4.
Troubleshooting a phone stream that goes sideways
Audio sounds distant. Bluetooth earbuds often route the mic to a low-quality channel. Wired or the built-in mic is more reliable for a stream.
Stream drops after a few minutes. Drop the bitrate one step (8000 to 6000, or 6000 to 4500) before blaming Twitch. Mobile uploads fluctuate.
Face cam is covering your HUD. Drag the bubble to another corner and pinch it smaller before you start, not mid-fight.
Calls and banners interrupt. Turn on Do Not Disturb. An incoming call will end a mobile stream faster than any bandwidth problem.
Android streamers who want a script running during a broadcast should read how do i screen record on android with a teleprompter?, since the teleprompter survives in Android’s Other App mode. For how the face cam compares to recording with system tools, there is also ios screen recorder with face cam: demoscope vs built-in.
DemoScope is worth a look if your streaming setup is literally one phone and you want your face on screen without a desk full of gear.
Frequently Asked Questions
Can I stream a mobile game to Twitch with my face on screen?
Yes. In DemoScope, use Stream mode with the Other App source so the broadcast follows you into the game, with the floating face cam bubble on top. On iPhone, touch indicators and the teleprompter are not available in that mode; on Android, the teleprompter, drawing and laser pointer still work.
Do I need a capture card or a computer to stream my phone to Twitch?
No. DemoScope sends RTMP directly from the phone to Twitch, so the only requirements are your stream key and a stable upload connection.
What bitrate should I use to stream my phone screen to Twitch?
4500 kbps video with 128 kbps audio at 30 fps is a safe default on home Wi-Fi. Drop to 2500 kbps on mobile data, and only try 6000 or 8000 kbps if your upload speed comfortably exceeds the bitrate.
Is the free version of DemoScope enough for Twitch streaming?
The free tier streams with a watermark and stops at 10 minutes per stream, including Other App streams, which is enough to test your setup. Pro removes the watermark and the time cap for $19.99 as a one-time purchase, not a subscription.
Can I stream to Twitch and YouTube at the same time from my phone?
No. DemoScope streams to one RTMP destination per session, so multistreaming to Twitch and YouTube simultaneously requires a different service built for that.
