See sound as it changes
• Read the live level on a large semicircle gauge from 0 to 120 dB.
• View a description of the level, such as 70 dB: Restaurant.
• Track session minimum, average and maximum levels.
• Follow changes on a scrolling 15-second chart.
• Pause, resume or reset your measurement. The screen stays on while measuring.

Save and share your readings
Save a measurement with its date, minimum, average, maximum, duration and nearest noise standard. History keeps up to 200 measurements. Share a saved measurement as text or delete it from history.

Understand the noise-level guide
Compare levels with examples from 10 dB breathing and 20 dB whisper through 60 dB conversation, 80 dB busy traffic and 120 dB thunder.

Calibrate for your phone
Adjust the reading from −30 to +30 dB to match a reference meter. Phone microphones vary, and readings are estimates. SoundScope is not a certified professional measuring instrument.

Audio stays on your phone
Audio is processed on the phone. No audio recording is saved or uploaded.

SoundScope is free with ads. Optional Pro is available as a subscription or one-time purchase to remove ads.
