You want to go live on YouTube showing something on your iPhone screen, with your face in the corner, and you do not want to buy a capture card or wire the phone into a Mac. The short version: YouTube's own mobile app will not stream your screen, so you need an app on the iPhone that takes a YouTube stream key and pushes screen plus camera over RTMP. DemoScope (HD Face Cam Screen Recorder on the App Store) does exactly that with its Stream mode.

**Short answer:** Use DemoScope's Stream mode to live stream your iPhone screen to YouTube with a face cam. Paste your YouTube stream key, pick YouTube as the platform, and DemoScope streams whatever it is displaying (a website, a photo, or a video from your camera roll) with your front camera overlay and touch indicators. It does not stream other apps or games running outside DemoScope.

## What DemoScope's Stream mode actually streams

DemoScope's Stream mode is an RTMP/RTMPS broadcaster built into the app. It sends what DemoScope itself is showing on screen, which is one of three sources: a website loaded in the app, a photo, or a video from your camera roll. On top of that it composites your front-facing camera bubble, touch indicators, and top and bottom text overlays, all of which go out in the stream.

That boundary matters. If you are demoing a web app, walking through a landing page, reacting to a video, or presenting slides exported as images, DemoScope covers it on its own. If you want to stream a native iOS app or a mobile game live, DemoScope is the wrong tool and I would rather say so now than have you discover it with 40 people watching.

## Step by step: going live to YouTube from your iPhone

1. In YouTube Studio (on the web or in the YouTube app's Live control room), create a new stream and copy the **stream key**. Set the stream to Unlisted while you test.
2. Open DemoScope and switch to **Stream** mode.
3. Choose what DemoScope will display: a website URL, a photo, or a video from your camera roll.
4. Turn on the face cam and set it up. Pick the camera shape (circle, square, vertical rectangle, horizontal rectangle), drag the bubble to the corner that covers the least important part of your content, and pinch to size it.
5. Add your top or bottom text overlay if you want a title or handle on screen during the stream.
6. Pick **YouTube** as the platform and paste the stream key.
7. Choose your video bitrate: 2500, 4500, 6000 or 8000 kbps, and audio at 96, 128 or 160 kbps. Output is 30 fps.
8. Tap start. Confirm in YouTube Studio that the ingest is healthy, then go live publicly.


Practical defaults from streaming off a phone regularly: 4500 kbps on decent Wi-Fi, 2500 if you are on cellular or hotel Wi-Fi. Jumping to 8000 on a flaky connection does not make the stream look better, it makes YouTube buffer. Plug in power too, because streaming with the camera running drains a battery fast and a phone throttling from heat mid-stream is the most annoying failure mode there is.

## The free way, and where it stops

The built-in iOS tools get you partway. iOS Screen Recording captures your screen and saves an MP4 to your camera roll, but it has no face cam and no touch indicators, and it does not broadcast anywhere on its own. The YouTube mobile app can go live, but it streams your camera, not your screen. So the free stack gives you either your screen with no face, or your face with no screen, never both at once.

| | DemoScope Stream mode | iOS Screen Recording + YouTube app | Mac + OBS with iPhone connected |
|---|---|---|---|
| Live to YouTube from the phone | Yes, via stream key | No (YouTube app streams camera only) | Yes, but the Mac does the streaming |
| Face cam over the screen | Yes, 4 bubble shapes, draggable | No | Yes, with setup |
| Touch indicators in the stream | Yes | No | No |
| Can stream other apps or games | No | No | Yes |
| Gear needed | iPhone only | iPhone only | Mac, cable, OBS config |
| Cost | Free with watermark and 10 min per stream; Pro $19.99 one-time | Free | OBS free, Mac not |

If streaming a game or a third-party app live is the actual requirement, use a computer with OBS and your iPhone mirrored into it, or a streaming app built on a broadcast extension. That is the honest answer, and it is not DemoScope.

## When to record instead of stream

Going live is not always the right call, and DemoScope's **Other App** mode (External PiP) is the reason I often record instead. Other App mode activates a system-wide floating face cam, sends DemoScope to the background, and records your screen across every app on the phone with your face visible, which is a rare capability on iOS. It records, it does not stream. For a product walkthrough that touches three different apps, record it in Other App mode, then upload the MP4 to YouTube as a premiere. You get the same reach without the risk of a dropped connection, and the file is already sitting in your camera roll ready for [repurposing screen recordings: turn one video into many](/blog/posts/repurposing-screen-recordings-multiple-content-pieces.html).

One limit to know: Other App mode has no touch indicators and no teleprompter, because iOS does not expose those outside the app. Those two tools only work during in-app recording and streaming. If you need a script scrolling while you talk, see [is there an iphone screen recorder with a teleprompter?](/blog/posts/iphone-screen-recorder-with-teleprompter.html) for how that fits together.


## Test the whole chain before you announce

Create an unlisted YouTube stream and run two minutes of it before the real thing. Check three things on the recording YouTube saves: is your voice coming from the mic you think it is, is the face cam bubble covering a button you need to tap, and is the bitrate holding steady. The free tier caps each stream at 10 minutes and adds a watermark, which is enough to rehearse; Pro removes both for $19.99 as a one-time purchase, not a subscription.

If you stream or record from a phone weekly, it pays to standardize the rest of the chain too, and [building a mobile video content creation workflow that actually works](/blog/posts/mobile-video-content-creation-workflow.html) plus the longer [mobile video content creation: a complete workflow guide](/blog/posts/mobile-video-content-creation-guide.html) cover the parts around the stream itself.

## Frequently Asked Questions

### Can I live stream my iPhone screen to YouTube for free?

Partly. DemoScope's free tier lets you stream to YouTube with a face cam but adds a watermark and caps each stream at 10 minutes. The built-in iOS tools are free but cannot do this at all, since iOS Screen Recording does not broadcast and the YouTube app streams your camera rather than your screen.

### Do I need a stream key, or can I just tap "Go Live" in YouTube?

You need a stream key. DemoScope connects to YouTube over RTMP/RTMPS, so you create the stream in YouTube Studio's live control room, copy the key, and paste it into DemoScope's Stream mode along with selecting YouTube as the platform.

### Can I stream a mobile game from my iPhone with my face on it?

Not with DemoScope. DemoScope's Stream mode only broadcasts what DemoScope itself displays (a website, photo, or camera roll video), and its Other App mode records other apps rather than streaming them. For live game streaming, use a computer running OBS with your iPhone mirrored in, or a streaming app built around an iOS broadcast extension.

### Does DemoScope stream to Twitch and Facebook as well as YouTube?

Yes. DemoScope's Stream mode supports Twitch, YouTube Live, Facebook Live, and any custom RTMP or RTMPS server. You cannot stream to several platforms at once, and there is no chat overlay in the app.

### What bitrate should I use for streaming from an iPhone?

DemoScope offers 2500, 4500, 6000 and 8000 kbps video with 96, 128 or 160 kbps audio at 30 fps. Use 4500 kbps on solid Wi-Fi and drop to 2500 kbps on cellular or an unfamiliar network, since a stable lower bitrate looks better to viewers than a high one that keeps stalling.
