Description
Show full descriptionShow less
Turn any screen into a karaoke machine. No box, no discs, no song packs to buy.
Start a room in seconds and show the QR code. Everyone searches and queues songs from their own phone, and the queue updates live for the whole room. Free, no ads, no account required.
HOW IT WORKS
1. Open KTV21 and start a room. No sign-up, no setup.
2. Show the QR code, or send the link. Friends join from their own phones.
3. Search a song, add it to the queue, and sing.
THE BIG SCREEN
Send the stage to your Android TV or Google TV and the video plays full screen while every phone in the room becomes a remote. Or keep the whole show on one phone or tablet — KTV21 works either way.
EVERYONE PICKS SONGS
No more passing one device around. Every guest browses, searches and queues from their own screen. Guests can pull their own song back out of the queue; the running order stays yours.
YOU RUN THE SHOW
Play, pause, skip and reorder from any device in the room.
ASK THE ASSISTANT
Tell the built-in assistant what you want and it does it — "find Bohemian Rhapsody and put it next", "skip this one", "what's in the queue". It drives the same controls you do, so you can keep singing while it works.
AUTO-DJ
Queue ran dry mid-party? Switch on Auto-DJ and KTV21 keeps the music coming, picking from the songs you have favorited and sung before.
FAVORITES AND PLAYLISTS
Star the songs that go down well and sort them into playlists. Sign in with Google to sync your favorites and history across every device — or stay a guest and skip signing in entirely.
28 LANGUAGES
KTV21 follows your device language automatically and searches in the script you type in. Sing in Mandarin, Japanese, Korean, Vietnamese, Hindi, Spanish, Arabic and more.
BUILT FOR SINGING
• Full-screen, distraction-free karaoke stage
• Rotate your phone to switch between browsing and singing
• The screen stays awake through every song
• Phones, tablets, Android TV, Google TV, and Android Automotive while parked
• Free, no subscription, no ads
Videos are provided by YouTube.
Gather everyone, pick a first song, and go.
