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.
Fall asleep fast, naturally, without disturbing others.

Just installed this app and paid 99 cents so it would have colors other than melatonin-suppressing blue. Then tried it out and discovered that it has only one breathing speed -- FAST -- in fact significantly faster than my normal resting breathing speed, so I'd be speeding up my breathing! I certainly don't think speeding up my breath rate that much would help me relax and go to sleep.

I was relaxed then an ad popped up after the 7 mins!!! Also paid to change colours. I don't understand why the default light is blue when blue light stops the production of melatonin which is essential for sleep! It should be yellow to mimic sunset and correct circadian rhythm. Would be 5 stars without ads (still pop up even after paying money!!!) and correct colour default.

Hello, first of all thank you for supporting the app. Would it be possible to use the contact info and send me screenshot of the ads that come up? You shouldn't get any, and there might be a bug that I can fix.
