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.
