Sleep Wind-Down
Twenty minutes to dim the day before rest.
A slow evening ritual. Deep brown noise and soft stereo tones ease downward while a horizon glow dims a little more with each phase, ending in near-darkness so you can set the app aside and rest.

Safety information
Light sensitivity
Some people may be sensitive to flashing or patterned light. Do not use visual modes if you have photosensitive epilepsy, a seizure history, unexplained blackouts, migraines triggered by light, or if a clinician has advised you to avoid flashing lights. The default PhaSona visual modes are designed to be gentle and low-risk, but no light-based experience can be guaranteed safe for everyone.
Headphones and volume
Binaural audio effects require stereo headphones. Keep volume comfortable and never use the app at painful or unsafe levels.
