Better sound starts at your seat

No special microphone. No account. Audio stays on your iPhone.
Requires iPhone with iOS 17 or later. Use AirPlay 2 for app-controlled readings, or your own player for a Quick reading or System Check. Phone-speaker mode is a demo.

With Room Tuner Reference, try one setting, component or placement change, then do a return check. See what changed and what to listen for. Save your preferred setup as the starting point for next time.
Play the Room Tuner Standard Sweep from any device while your iPhone listens. A free Quick reading gives the same Room score and guidance, including with wired, optical and other systems.
Room scores ignore frequencies below your speakers’ natural bass reach. Older readings are re-scored for display only, preserving the original record.
The room is part of the system
Walls, corners, furniture, and the exact place you sit can pile up one bass note and erase another. Room Tuner helps you understand that effect without needing to become an acoustician.
How it works
A simple loop that puts the useful answer before the acoustic method.
Choose an AirPlay 2 speaker, receiver or Apple TV for app-controlled readings. For a Quick reading, choose Just listen and play the Standard Sweep from your own player. System Check also offers Use my own player.
