Free, ad-free, and account-free. If Sossego helps, an optional contribution supports its upkeep.

Choose an intentionally synthetic soundscape and, if you like, a subtle beat pattern. Use headphones for binaural beats; the speaker mix also works with headphones.

People respond differently. Choose what feels comfortable, keep the volume low, and stop if the sound is unpleasant. Specific frequencies do not guarantee calm or focus.

Follow a gentle breathing guide and hum on the exhale, at any comfortable pitch. You can also follow the guide silently.

Do not strain or force your breath to match the guide. Return to normal breathing if you feel dizzy, breathless, or uncomfortable.

Ambient offers sparse tones, Pink noise masks surrounding sounds, and Textures adds soft procedural tapping and brushing. Choose what you find restful.

Timed sessions can fade to silence. Playback may be interrupted when your device locks or the browser is in the background.

Sound becomes brighter or warmer with the time of day and, on supported devices, ambient light. This changes the sound's character, not its effectiveness.

Sossego never uses your microphone. Light readings stay on your device and are not saved.

Use a comfortable, low volume. Only close your eyes or follow a breathing guide when it is safe to pause, never while driving or operating machinery. Stop if you feel uncomfortable.

This is a wellness tool, not a medical device or a substitute for professional care. Ask a qualified clinician if you have concerns about sound or breathing exercises, persistent anxiety, or sleep difficulties.

Optional, private, and only saved on this device. Choose a score to record it.

Breathe in comfortably. Hum softly as you breathe out, at a pitch that feels natural. There is no need to match the sound or extend your breath.

Follow the words or the visual guide. If it feels uncomfortable, stop and breathe normally. Silent practice follows the same guide without audio.
