## What is Sleep Clock?

Get more sleep with the Kid's Sleep Clock. If your child is waking up too early because they don't know if it's time to wake up yet this is the app for you. The app provides a visual alarm; the clock face glows blue when it is time to sleep, and yellow when it is time to wake up. Great for kids who can't tell time. There are also short-term green and red modes that can be used to set short-term timers (like quiet time or time-out). Since it glows all night long, it also acts as a nightlight; you can set the brightness of your device to whatever you want. Since the light will stay on all night, it is recommended that you plug your device.

The app works best for kids that are 2+ and can be taught that they should 'stay in bed when the clock is blue'. The app can optionally display the digital time on the face if your child is a bit older. Alarm sound is optional; if your child is a heavy sleeper in the morning and needs to be woken up, this will do the trick. But if you want to let your son or daughter sleep in, don't set the alarm at all! Dedicated clocks usually cost $40 or more, this is an inexpensive way to see if this can work for your family and help you get more of that precious morning sleep!

### 1/5 — Don’t waste your money!

*2021-06-07*

If I could give this app ZERO stars, I would! I just wish I would have read more reviews before I purchased. I set the sleep alarm for 20:00 and the screen turned navy at the right time. I set the awake timer for 07:00 and went to bed. My kid woke me up at 05:05! I told her it wasn’t 7 yet and she said, “but you said to get up when the light is yellow!” Nothing I tried would fix the wake color so, here we are - sleep deprived and grumpy.

**Developer response:** Sorry about these troubles. This was caused by an unusual timezone issue that only showed up in a few devices and has been fixed now in the latest version in the App Store.

### 1/5 — Doesn’t work, support not available

*2020-12-27, version 3.1.1*

Clock shows the right time, but the alarms go off at the wrong times (not the specified times). Not sure what is wrong with it. My kids got the yellow screen on christmas morning at 3am but it was supposed to go on at 7am.

### 1/5 — Doesn't work

*2020-06-15*

I set up the clock to show green at 7:00am and got woken up by my daughter at 5am! because the clock was showing green.

 Getting the time right is the only thing I want from this app, and I'm quite annoyed it didn't work.

**Developer response:** We are sorry about the trouble; this was caused by a rare timezone issue and has been fixed in the latest version of the app.

### 1/5 — Does not work

*2020-04-30*

I bought this app because it looked like it was just what I needed to help my kids stay in bed. It doesn’t work! I set the awake for 6:30 thinking that means am and the sleep for 19:00 thinking that means 7:00am. At 7pm it changes to the sleep color I picked and I was excited because it was working perfectly. Them at 2am I hear my children talking. The light had changed to green which was the get up color and they were up. 2:00am!!!!
I have tried to figure out how to get it to turn green at 6:30 instead of sometime in the middle of the night and can’t figure it out.
Do not waste your money on this app!

**Developer response:** We are sorry that the app did not work properly for you. We have identified and fixed a rare timezone issue that caused this problem and has been updated in the App Store.

### 1/5 — Glowing blue nightlight is about the worst thing you can choose

*2017-03-26*

It seems really odd that you can't choose the colors on the clock, only on the timers. Being forced to have blue as he nighttime color is a bad choice.  Blue light impairs sleep.  It would be much better if they stuck with standard colors of red and green for stay in bed versus versus wake up time.  Also, the display times out, contrary to the application description.

**Developer response:** Hi, we have added the ability to choose from one of 12 colors to make this selection more customizable for you.

### 1/5 — Horrible

*2016-11-22*

Don't waste your money. Screen does not remain on as stated. I have downloaded on 2 iPads so far and both screens go black. There are no instructions on how to use. Not user friendly. We have a ready to wake clock at home that we use with no problems. This app is a joke!!!!

### 3/5 — Color options

*2015-10-03*

5 stars if I could change the alarm wake up color to green. Then it would match the clock we use at home. This app is just for traveling.

**Developer response:** Thanks for the positive review! We have added the ability to choose the colors based on your preference so you can now choose just what you want!

### 5/5 — Works like a charm!

*2014-05-07*

Love this app. It's simple and effective. We use it when we travel and it makes my life so much easier. Instead of my 3 and 5 year old asking me if it's time to get up every 2 minutes they know to just lay quietly in their bed til the clock turns yellow. The $30 ok to wake clocks all freak my kid out with their animated characters and creepy suns and moons with faces. This one is simple and non-creepy which works with my sensitive kids. :)

### 4/5 — Good app

*2014-04-20*

I like this app. It helps when we travel. We have a different clock dedicated for this at home.  I would give the app five stars if I could change the colors.  I would like red for when my son needs to sleep and green for when my son needs to get up. I can make the red work when using the nap timer but it's not as easy.

Overall, it is a good app!

### 5/5 — Loving the extra sleep

*2014-03-09, version 2.1*

This is great. Our kids know when to stay in bed and when to wake up. On vacation it is especially nice because it works with the devices we have with us. My parents also use it solely for a large-number clock.
