Quell Control Center

Quell-Control Center is the companion app for Quell acoustic-privacy devices. Set up, control and monitor your Quell hardware over Bluetooth — no account required.

Discover nearby devices, then fine-tune how they sound: • Volume, presets and mute • Masking soundscapes (white / pink / brown noise, rain, ocean and more) • 8-band equalizer to shape the sound • Adaptive mode that follows the room's noise level

Get going in seconds with a guided setup wizard, connect your device to Wi-Fi, and keep it current with over-the-air firmware updates.

Advanced features: • Mesh — link several Quell devices so they coordinate • Privacy-Glas — mask a window pane against eavesdropping • Manage on-device audio files and system sounds • Built-in help & guides for every feature

Available in English, German, French and Spanish.

NOTE: Quell-Control Center requires a Quell device to control. To explore the whole app without hardware, open Help → Demo Mode.
