HONEST ABOUT ACCURACY
Hush shows an approximation based on your phone's microphone. Readings vary by device, case and position, and must not be used where a certified sound level meter is required.
NOTHING LEAVES YOUR PHONE
Hush reads the level of the sound in real time. No audio is recorded or saved. Your measurements never leave this phone. Hush works fully offline.
Payment is charged to your Apple Account. The subscription renews automatically unless you cancel at least 24 hours before the period ends. You can cancel any time in Settings inside this app.
