## What is Night Wave Light?

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.

### 5/5 — Worth it

*2018-06-30*

Yes, it's worth the $1 to try it. You could spend $60 for a device that does the same thing to find out if that works, or you could try this one for a buck. 1 star reviews are dumb if it didn't work for you - the app just saved you $59.

### 3/5 — Good app but too quick

*2016-03-25*

Please can we have the choice to slow it down to 60bpm or a speed that we are comfy with in the next update?

### 4/5 — Cured!!

*2015-05-04*

I deal with occasional insomnia due to stress, this app cured me! Instead of staring at the ceiling for hours, I turn this on and am out in... Well less then 7 minutes, not sure exactly but I never see the end of the cycle. :)

Update: still love the app, but I've realized the cycle ends on bright blue. It would be much better if it ended on a black frame, I fear this is damaging my phone & causing it to be hot all night with the screen lit.

### 1/5 — Waste of money

*2014-09-28*

All the all does is flash a blue light on the screen. This actually keeps me awake instead of helping me sleep. I am very disappointed.

### 1/5 — $ BACK PLEASE!

*2013-10-03*

The light technique worked great getting me to sleep, BUT when I woke up 4 hours later (my insomnia is pre-sleep & mid cycle) & tried to use the App it refused to work.
Fix the crash!  Or, give me my $ back!!!
I had to down load a similar App that works great.

### 1/5 — Didnt work

*2013-09-06*

I tried the 14 min first. The another 7 mins. Then the 21 mins. None worked for me. I was still awake for another 2 hours after all of that. My breathing was also difficult to sync with the light. Also, are you supposed to look at the screen or the ceiling?

### 4/5 — Works ok

*2013-05-19*

Would like in app brightness features instead of editing phone settings.

### 5/5 — Nice!

*2013-01-23*

I was leery at first afraid this would somehow interrupt sleep or give me headaches but it simply lulls me into a very natural sleep. I set it for 14 minutes but I imagine less than 7 would do. Some nights I just could not quit thinking long enough to go to sleep. This is a great help!

### 5/5 — Drug-free sleep

*2012-09-19*

It works!! Just the same way you unconsciously sync your breathing with someone else's when you're lying next to them, you start breathing in time with the light. I've never made it the whole 7 minutes. I think blue was a good choice of color too.

### 5/5 — Perfect

*2012-08-18*

This app perfectly implements the pattern and light of the more expensive (and I assume unaffiliated) device. For 1/50th of the cost of that device, this app has given me the best night of sleep I've had in a very long time. I spent $2k on a new mattress, and this little $1 app solved my insomnia.  Unspeakably amazing ...
