iOS and Android streaming is popular, but caption options are limited. Here's the honest breakdown of what's possible — and how to get the best captions from a mobile streaming setup.
Start Free TrialMobile streaming has become increasingly capable. Apps like Streamlabs Mobile, StreamYard (browser-based), TikTok Live, Instagram Live, and YouTube Live all work directly from iOS and Android. But adding custom caption overlays to mobile streams is significantly harder than desktop streaming, for one fundamental reason: there's no OBS on mobile.
OBS Studio (Open Broadcaster Software) is the standard tool for adding Browser Source overlays — including StreamTranslate captions — to live streams. It's a desktop application. On mobile, you're at the mercy of whatever caption functionality the streaming app or platform provides natively.
That said, there are several approaches available, ranging from "works great" to "acceptable limitation." Here's the complete picture.
The single most effective solution for mobile streamers who want captions is to stop streaming purely from the phone and move to a PC-based setup, even a minimal one. A laptop running OBS with a webcam can replace your phone camera, and StreamTranslate captions work perfectly. This isn't always feasible, but if you stream regularly, the desktop setup pays back in production quality and caption support.
StreamYard (browser-based, works on iOS/Android via Chrome) supports adding overlays to your stream, including custom browser source URLs. This means StreamTranslate can potentially work via StreamYard on mobile. The limitation: StreamYard controls audio capture, and StreamTranslate needs access to your microphone audio. Testing required for your specific setup.
TikTok has auto-captions for live streams in some regions — viewer-controlled, English-centric. Limited but available.
YouTube's auto-captions are available on mobile live streams but are delayed, English-only, and inconsistently accurate. Not ideal but present.
Instagram has added auto-captions for Reels but mobile Live streams have minimal caption support as of 2026.
If you want to use your iPhone as a camera for OBS on a desktop computer, you can use iPhone Camera for OBS or similar apps to mirror your iPhone camera feed into OBS on your Mac or Windows PC. Your audio is captured by OBS via a desktop microphone or the iPhone's audio feed. StreamTranslate then works normally in OBS. This setup gives you mobile camera quality with desktop OBS capabilities — including full StreamTranslate caption support.
OBS Studio is free. Install it on any Mac or Windows computer, even a modest laptop works for captioned streaming.
Apps like Camo (iOS) or DroidCam (Android) let you use your phone camera as a webcam source in OBS via USB or Wi-Fi. Your phone's camera quality is now in OBS.
Go to streamtranslate.live/setup, get your browser source URL, and add it to your OBS scene. Your phone camera feed gets captions automatically.
Configure your OBS stream output for TikTok, YouTube, Twitch, or wherever you stream. Mobile camera quality + desktop OBS capabilities + StreamTranslate captions.
Streamlabs Mobile is the most popular dedicated mobile streaming app. As of 2026, it does not support custom Browser Source overlays in the same way desktop OBS does. It has some pre-built overlay templates, but StreamTranslate's custom URL method isn't supported natively. This means pure Streamlabs Mobile users can't use StreamTranslate in the typical way. The workaround remains the desktop + mobile camera approach described above.
If you're a dedicated streamer who wants proper caption support: invest in a basic laptop running OBS and use your phone as a wireless camera. You get the best of both worlds — your phone's camera and the full power of OBS with StreamTranslate captions. If you stream casually from mobile only: rely on the platform's native caption options (TikTok or YouTube's auto-captions) with the understanding that they're limited. The gap in caption quality between desktop OBS + StreamTranslate and mobile-native captions is significant.
StreamTranslate requires OBS, which is a desktop application. For iPhone TikTok Live streaming, you'd need to use your iPhone as a camera source in OBS on a Mac or Windows computer using an app like Camo.
Streamlabs Mobile doesn't support custom browser source overlays like StreamTranslate. Options are limited to platform native captions. For full caption support, switch to desktop OBS.
Yes. Use OBS with a phone screen capture (via USB/DroidCam/Camo) and add StreamTranslate as a Browser Source. Your phone content is in OBS and captions appear over it.
Yes, YouTube has auto-captions for live streams including mobile, but they're delayed, English-only, and not customizable by the streamer. They're better than nothing but less accurate and reliable than StreamTranslate.
Any Mac or Windows computer made in the last 6 years running OBS can handle StreamTranslate. Even a budget laptop works — the caption processing happens on StreamTranslate's servers, not your computer.
Instagram Live has very limited caption support as of 2026. For production-quality captions on Instagram content, stream via a computer with OBS if possible, or use Instagram's basic viewer-side caption features.
