6 best live streaming apps for iPhone Duo
Stream to YouTube, Twitch and custom RTMP from iPhone Duo with these six apps, from pro protocols to creator overlays.
iPhone Duo has the camera, the Wi-Fi 7 and 5G connectivity and the vapor-chamber cooling for live streaming. Long streams still produce heat, so read our overheating guide first. These six apps cover pro streaming protocols, creator overlays and simple go-live buttons.
1. Larix Broadcaster: best for pro protocols
Larix supports RTMP, SRT and more, with fine control over bitrate and encoding. It is free, with premium options, and it is the technical pick.
2. Streamlabs: best for creator overlays
Streamlabs adds alerts, chat and scene overlays for Twitch and YouTube. It is free, with an Ultra subscription.
3. PRISM Live Studio: best for casual streams with effects
PRISM offers filters, effects and multi-platform streaming. It is free and easy to start with.
4. YouTube: best for going live on YouTube
The YouTube app can go live directly, subject to YouTube's eligibility rules for mobile streaming.
5. PromptSlate Studio: best for rehearsing and recording the replay clip
Our app. PromptSlate Studio is not a streaming app. Creators use it around the stream: rehearse your opening with the teleprompter, or record a scripted trailer or recap clip to post afterwards. It is in final development for iOS 27.1 and will be a $9.99 one-time purchase.

6. Twitch: best for going live on Twitch
The Twitch app streams straight from the camera with chat on screen. It is free.
The bottom line
Use Larix for control, Streamlabs for overlays and PRISM to keep things simple. Keep the Duo plugged in and out of direct sun on long streams.
