Noizly

Noizly helps users understand ambient noise levels around them in everyday situations. With one tap, the app starts live monitoring and shows the current decibel level, average level, peak level, waveform, and history trend. When surrounding noise stays above the threshold you set, the app can show a visual alert and, if enabled, send a local notification while the app is in the background. If Evidence Recording is turned on, Noizly can also save local WAV clips for threshold-exceeding noise events so they can be reviewed later in History. The app does not require account registration. Settings, noise history, and evidence clips are stored locally on the device by default, making the app suitable for commuting, office work, rest time, housing, and neighborhood noise self-check scenarios.
