## Sleep Calculator Pro Description
Good day starts with good morning!  Go to bed at the right time and wake up in between your natural 90-minute sleep cycles to feel rested and refreshed.  A good night's sleep consists of 5-6 complete sleep cycles.

◦ Select when you want to wake up
◦ Calculate your best time to go to sleep
◦ Calculate the best time to wake up

It takes an average human about 15 minutes to fall asleep.  If you wake up at one of the calculated times, you'll rise in between 90-minute sleep cycles.

Sleep Calculator helps you decide when to go to bed so that you can wake at a specific time ensuring a good night’s rest, or what time you should wake up if you want to go to bed right now.

If you want to determine your real sleep cycles - our Sleep Tracker functionality allows you to track and analyze your sleep and, if done correctly, will show you your sleep progress – when you were in light, deep or REM (dream) sleep phase and the breakdown of your sleep cycles.  Snoring/noise detection can be enabled as well.

Our brand new Smart Alarm will wake you up easy in the lightest sleep phase, making sure you wake up easy and rested.

Bedtime notifications can also be set up so that you do not miss a proper time to go to sleep.

## Sleep Calculator Pro Reviews in United States

### ***** "straight forward, easy to use"
no adds, no bright screen. Open the app. Put in the time I want to wake up and hit calculate bedtime.
-- little 8th, 2024-12-13

### ***** "10/10"
I Love this app!
-- archy marshal, 2023-08-10

### ***** "Review"
This app is free and one of the best out ther and is for freeee and has all the trends and stats.
-- jddhjdjskskskekjejennxnx, 2021-07-29

### ***** "best app you can get for smart alarm"
I usually never write reviews for apps, but this app is just so amazing that I felt obligated to. 

It’s a super simple interface, and it has all the information you need to calculate when to go to sleep/wake up. It also tracks your sleep through sound and movement (which I don’t utilize as much, because sleep trackers tend to be a bit inaccurate at times). You can set up notifications to remind you when you should sleep and I prefer it over the default bedtime feature. And all of this is free!!
-- driving comf, 2021-02-02

### ***** "Free version is GREAT and has everything you need"
This app is the epitome of what a free version should look like. It functions perfectly fine and has all the advertised features available in the free version- calculator, alarm, sleep sounds- but if you’d want more sounds for alarms or white noise, there is the paid option. Love that you can make it super customized. Not everyone falls asleep at the same rate, and you can change that so it can calculate a more accurate bedtime. If you’re trying to maintain a better sleep schedule, this app is a must have.
-- ren.png, 2020-11-23

### ***** "Simple but works"
It’s very quick and easy
-- Lenel522, 2020-01-31

### ***** "SIMPLE!!"
so simple and easy to use. it EVEN TELLS U WHEN TO GO TO BED! NOT SLEEP BUT GO TO BED. i learned a bit of info that i didn’t know but it’s quite simple and it’s helpful when trying to actually getting a good night sleep
-- Soilderboy49, 2019-08-21

### ***** "AMAZING"
I’ve been using Sleep Calculator for about a year now and I am absolutely in love with it. This is an app I will use until the day I die !! The only confusing thing is when it says that it takes an average person 15 minutes to fall asleep, and goes on to say that if I were to go to bed right now I would wake up well rested at following times. Although I don’t know if I were to fall asleep in 15 minutes that the times I would wake up well rested would still be the same times. Please clarify !!!!!!
-- yooper12345678910, 2019-06-12

### ***** "Simple and Effective"
This app is very easy to use and every time I put my alarm at a time it says to wake up at, I wake up easily and well rested.
-- efirnfofowks, 2019-05-11

### ***** "The best one. Period."
Simple, to the point, accurate
-- Lia_419, 2019-02-16
