FAQ
Sleep sounds app FAQ
What is a sleep sounds app?
A sleep sounds app helps you play calming audio designed to support bedtime routines, relaxation and a quieter mental state before sleep.

Calma focuses on personalized soundscapes, a simple interface and a calm premium feel instead of overwhelming you with too many layers of complexity.
Can I build my own sleep mix?
Yes. Calma is designed around creating your own relaxing audio mix rather than only choosing one fixed track.
What is the best free sleep sounds app?
The best free sleep sounds app lets you customize your own sound mixes rather than playing a single fixed track. Calma offers a generous free tier with white noise, brown noise, rain, and nature sounds — all without ads that wake you up. It works completely offline and doesn't require a subscription.
Are sleep sound apps safe to use every night?
Yes, sleep sound apps are safe for nightly use as long as the volume stays below 60 dB (about the level of a quiet conversation). Over time, your brain associates the sound with sleep, making it easier to fall asleep quickly. Keep your phone at least 2 meters from your head.
