Frequently asked questions
Is the app free?
Yes. Karapp Müzik is free and supported by ads. The full-screen app-open ad is never shown while music is playing, and there are no ads on the player screen.
Are my songs uploaded to a server?
No. Your songs stay on your phone. If you create an account, only your app settings and profile (name, email) are kept in the cloud.
Do I need an account?
No. An account only syncs your settings across devices. Sign in with Google or Apple and delete your account from the app whenever you like.
Which file formats are supported?
MP3, AAC/M4A, FLAC, WAV, OGG and other formats your device supports; M3U/M3U8 playlists.
How does listening in sync work?
One phone starts a session and shows a 4-digit code. Nearby phones join with the code and play the same song at the same moment. No internet needed; devices talk over the local network or Bluetooth. Android and iPhone cannot pair with each other yet.
How do I change my ad preferences?
In the app: Settings → Ad preferences. If you don't allow personalized ads, ads won't be chosen by your interests. Ads never appear while music plays or on the player screen.
