CelLink — the companion app for your CelAudio / CelMusper music system. CelLink finds every CelAudio and CelMusper device on your local network automatically and puts them one tap away. No setup, no account, no clutter — open the app and your gear is right there. Features • Automatic discovery — CelLink uses standard mDNS/Bonjour to find your devices the moment you open the app, even on networks that filter multicast. • One tap to control — tap any device to open its full control interface instantly. • Add by IP — device on a different subnet or not showing up? Add it manually by IP address. • Made for iPhone and iPad — a responsive layout shows one device per row on iPhone and two to three across on iPad. • Also on Mac — the same experience across your Apple devices. Privacy first CelLink has no account system, no ads, and no third-party analytics or tracking. Device discovery happens entirely on your local network, and nothing personal ever leaves your device.
