About this app

Night Wave Light turns your phone into a gentle breathing light that guides you to sleep naturally. No sounds, no headphones, no expensive gadgets. Just soft, pulsing light that slows your breathing and calms your racing mind.

How it works:
Place your phone on your bedside. Watch the soft blue light pulse on your ceiling. Breathe in as it brightens, breathe out as it fades. The light gradually slows, guiding your breathing from alert to asleep—usually in under 7 minutes.

Why it works:
Slow, rhythmic breathing activates your body's natural relaxation response. By focusing on the light instead of your thoughts, your mind stops racing. Your heart rate drops. You drift off.

Perfect for:
• Light sleepers sharing a bed—completely silent
• Anyone tired of white noise apps and sleep sounds
• People who've tried meditation apps but couldn't focus
• Those seeking a natural alternative to sleep aids

What you get:
• Customizable session length (7-30 minutes)
• Adjustable breathing pace (slower to faster)
• Choice of light colors
• Auto-shutoff when session ends
• Works in any dark room

Place it down. Watch the light. Wake up rested.
