★★★★★Rated 4.2 ★ on the App Store
Backing track + live vocals on the same speaker
Start your favorite karaoke track on YouTube, Spotify or Apple Music, then go live with ShareMic. Both the music and your voice play through the same connected speaker, so the whole room hears the performance — no mixer or PA needed.
A karaoke microphone app for your portable speaker
Looking for a karaoke app that lets you sing through a portable Bluetooth speaker while the music plays? That's what ShareMic does, with one difference worth knowing: it isn't a song library, it's the microphone. Keep the karaoke videos and backing tracks you already use on YouTube, Spotify or Apple Music, and ShareMic plays your live voice over them — the music and your vocals come out of the same speaker.
Pick a Bluetooth speaker for singing
For karaoke, a Bluetooth speaker is the best match: Bluetooth has much lower delay than AirPlay, which is why it's the one to use for live singing. AirPlay offers higher audio quality but can add up to about two seconds of delay, which makes it hard to sing along to the music.
No karaoke machine required
You don't need a dedicated karaoke machine or a wired mic. Your iPhone is the microphone, any Bluetooth or AirPlay speaker is the PA, and any music app supplies the backing track — a complete karaoke setup from the phone in your pocket.
Sound like a pro: reverb, effects and clean vocals
Add a Hall or Cave reverb for that stage sound, or switch to Robot, Alien and Chipmunk for comedy rounds. Apple's Voice Isolation keeps background noise out of your mic so every word lands — and if you try to use the iPhone's own speaker as the PA, ShareMic warns you about feedback and suggests headphones or an external speaker.
Free to download, ready in seconds
ShareMic is free to download and the live microphone works out of the box — no account needed. Unlock all the voice effects and recording whenever you want with ShareMic Pro.
