No audio is recorded or saved - Keep sounds playing in the background when your phone is locked The controls stay simple and easy to read in low light. Start a sound, change the volume, set a timer, and get back to resting without digging through menus. Noctra is a comfort audio app. It does not provide medical advice, diagnosis, or treatment.
