Privacy: Audio never leaves your device. Mic Test does not record, save or upload your voice. It only measures the sound level while the test is running.
Good to know: Mic Test measures the sound your iPhone or iPad receives. It does not test speakers or the camera. Results depend on your device and its mics. The free version shows ads; Premium removes them. You can restore a previous purchase from the app's Settings.
