RoomCast Live sound from your iPhone,
straight to people's phones.
RoomCast Go broadcasts your iPhone's microphone, a headset or a USB sound card over the local Wi-Fi. Listeners scan a QR code and listen in their phone's browser, on their own earbuds or headphones.
For iPhone with iOS 17 or later. Free, with an optional Pro upgrade. The delay is usually around half a second.
How it works, in three steps
- 1
Pick your sound
The iPhone's microphone, a wired headset, or a USB sound card or line-in from a mixer or DJ desk.
- 2
Go live and show the QR code
Give the broadcast a title and start it. RoomCast Go shows a QR code and a link for listeners.
- 3
Listeners scan and listen
On the same Wi-Fi or your iPhone's Personal Hotspot, people scan the code and listen in their phone's browser.
What RoomCast Go does
Broadcasts from your pocket
Send the iPhone microphone, a wired headset, or a USB sound card or line-in to every listener on the same Wi-Fi.
Listeners use their browser
People scan a QR code or type a short link. The listening page comes from your iPhone and opens in their phone's browser.
A title people recognise
Name your broadcast, for example the event or the language, and listeners see that title on their page.
Speech or music
Mono or stereo, plus a 96 kbps Music quality option for music.
Glanceable while live
A Live Activity and the Dynamic Island show that you are on air, and the background moves with the music.
Warns you about Wi-Fi changes
If the Wi-Fi drops or your iPhone's address changes, RoomCast Go alerts you and shows a new QR code to share.
Where people use it
Silent disco
Feed a DJ desk or mixer in through a USB sound card, and guests dance on their own earbuds.

RoomCast Go and RoomCast for Mac are two separate apps. They don't connect to each other: each one runs its own broadcast.
RoomCast Go for iPhone
Broadcast from an iPhone using its microphone, a wired headset or a USB sound card. Handy when you want a small, portable setup.
RoomCast for Mac
A free, open-source Mac app that streams live audio from a Mac over local Wi-Fi to listeners' phones, with a printable QR poster.
With both apps, listeners do the same thing: join the Wi-Fi, scan the QR code and listen in their phone's browser.
