SoundMeter

SoundMeter is a clean, fast decibel meter that uses your phone’s microphone to measure environmental noise in real time.

No subscription. No fake “pro” wall. No cluttered UI. Just a reliable sound meter when you need to check noise levels quickly.

Why SoundMeter?
Most sound meter apps are overloaded with ads, confusing screens, and aggressive upsells. SoundMeter is built to be the opposite: simple, readable, and pleasant to use.

Features
• Real-time sound meter for measuring noise in dB
• Clear animated gauge with easy-to-read live values
• Noise level categories from quiet spaces to dangerous volume
• Live min, average, and max readings during each session
• Session history saved automatically on your device
• Calibration offset to better match a reference meter
• Export history as CSV
• Works offline for core measurement features
• Clean light and dark theme

Useful for
• Checking room noise
• Measuring office, home, or street sound levels
• Monitoring rehearsal or practice volume
• Documenting noisy neighbors or appliances
• General decibel and noise level checks

Privacy
SoundMeter does not record or store audio files. Audio is processed in real time on your device to estimate noise levels, then discarded.

Important note
Phone microphones vary by device, so readings may differ from professional sound level meters. For best results, use the calibration option to match a known reference.

Permissions
• Microphone: required to measure environmental sound
• Internet: used only for ads, if enabled

SoundMeter is built for people who want a modern, no-nonsense decibel meter that just works.
