WHAT THE HECK I SPENT 4 HOURS STARING IN THE PHONE AND DID WHAT IT SAID AND NOTHING HAPPENED!!!!!!!!

★★★★★Dec 24, 2018

bad

★★★★★Dec 19, 2018

Love the app i wish more colors were free.

★★★★★Jul 21, 2018

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.

★★★★★Jun 23, 2018

I hate this for my own reasons I just don't like how you have only 1 option untill you pay and when you pay it's probably not even gonna be much better according to other reveiws

★★★★★Oct 2, 2017

This app is great. So simple but absolutely does the job and puts me to sleep every time. Even if you don't drop off, it really helps you to control your breathing and relax. Love it!

Store description

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.
