## What is Hush?

How loud is it, really?

Hush turns your iPhone into a simple sound level meter. Point it at the noise and you get a big, readable number in decibels, a clear gauge, and a plain-language label telling you what that level actually means — from a library to a live concert.

FREE
• Real-time level with a clear gauge
• Minimum, maximum and energy average (Leq)
• A-weighted (dBA) or unweighted, Fast or Slow response
• Your recent measurements, saved automatically

HUSH PREMIUM
• No ads, anywhere in the app
• Unlimited measurement history
• Detailed graphs with axes and averages
• Export your data as CSV
• Long and background measuring
• Fine calibration in 0.1 dB steps
• Home Screen widgets

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.
