KTV21: Karaoke & Music Videos

RaveLab, Inc.

About this app

KTV21 turns any screen into a karaoke machine — your phone, tablet, or Android TV.

Start a room in seconds, search for songs, and sing along to music videos with the whole group. No song packs to buy, no subscription, and no account needed to start.

🎤 Sing anywhere
Run the whole show on one phone or tablet, or send the stage to your Android TV and turn your phones into wireless mics and remotes.

📱 Everyone picks songs
Share the room's QR code and every guest can search and queue songs from their own phone. No more passing one device around.

🔎 Endless songs
Search a huge world of music videos and sing-along tracks. Build the queue, reorder it, and keep the party going all night.

👑 Host controls
The host runs the show — play, pause, skip and reorder — from any device in the room.

⭐ Favorites & history
Sign in to sync your favorites and recently sung songs across devices, or jump in instantly as a guest.

🌍 Your language
KTV21 speaks 20+ languages and adapts to your device automatically.
