Your iPhone builds a 3D map of your rooms while the microphone paints sound onto it. Every room gets a Quiet Score, so you can find the best spot for sleep, work or the baby.
Walk through your home and watch a 3D model of it build live.
Loudness is mapped onto your actual floor plan. Calm where it is quiet, hot where it is loud.
Everything stays on your iPhone. No account, no cloud, and audio is never recorded.
