AutoSleep, the best app for monitoring sleep with the Apple Watch

One of the most requested functions for Apple and specifically for its watch is sleep monitoring . This is a highly expected feature to have information on how the night is spent and all the events that may occur. Until this feature arrives you must resort to third party applications and one of the best is AutoSleep.

First steps

As soon as you enter the application for the first time, you should take a questionnaire about your bedtime habits. One of these habits is if you use the Apple Watch while you sleep. This is very important, as accurate monitoring is done while wearing the Apple Smart Watch. Thanks to the sensors it includes, a measurement of your heart rate is taken, as well as the movements you make in bed.

In these first steps, the application will explain the different functions that you will see in the interface. By following a color pattern, as if it were a traffic light, you will quickly know how you slept. The ideal is always to have an excellent sleep, but sometimes the sleep is not always perfect.

Representation of the dream

Sleep monitoring is embodied in a clock that records for hours how you slept, emphasizing deep, quiet, light sleep and also when you woke up in the middle of the night. Thanks to the movements you make, the application will know what stage of sleep you are in. The heart rate also plays a crucial role, as the representative clock shows the average heart rate but just below, where it indicates the sleep session, it is broken down in more detail with a graph that you can manipulate to see what was happening at a particular time of the night.

In this same report you will find the breakdown of hours you have been in each of the stages of sleep and also the efficiency. Even if you sleep 8 hours, these can be totally inefficient because they are not totally deep and very light. This can clearly be explained if you wake up very tired by yourself.

In this same report, if you have an Apple Watch Series 4 or higher, it details the amount of ambient sound that has existed in the room where you have slept. There are several ranges from a quiet bedroom to the sound of a lawn mower.

One of the most interesting and comical features of this application is undoubtedly the sleep bank it includes. Just like owing money to a real bank, you can also owe hours of sleep. If you mark that every night you must sleep 8 hours but you don’t, the next morning you will see that you have a percentage of hours in debt. This will help you to set yourself up in a more efficient way so that at the end of the week you will have slept the recommended 8 hours to be healthier.

In the watch we mentioned at the beginning where the sleep events are clearly presented at different times, there is a series of rings. These are very reminiscent of those in the Apple Watch Activity, and should always be filled in for optimal sleep. These rings include the hours of sleep, the hours that you have slept with optimal quality or the hours that you have slept deeply. The drop in heart rate is also a parameter that is counted in this ring system, since it is vital to lower the heart rate during sleep to make it deep. If you click on these rings you will see in much more detail how this parameter and the medical definition can be completed.

All these parameters can be accessed from the ‘Today’ tab at the bottom of the application or through the notification that will inform you every morning when you wake up.

Apple Watch autonomy compromised?

One of the big questions you can ask yourself is what impact this application will have on the autonomy of the Apple Watch. Obviously, collecting and sending data all night long, makes the autonomy suffer. But the truth is that the efficiency of this application makes it hardly noticeable. It will force you to have other load parameters, since not being able to do it during the night you will have to resort to load at another time of the day. But for all the data it offers, this is an extremely efficient service in this sense.

Edition and calibration

Sometimes the result you get from the application is not the most correct because you know you have woken up or gone to sleep at a different time. That’s why when you access the information of the day, in the clock, at the bottom left you will see a small pencil. By clicking on this you can select another analysis that makes the application of your dream to see if it is correct. It is important to note that of the ‘calculation’ that makes the app always choose the one that may be more accurate but can fail. When you choose the data that fits the reality, this will act as a way to calibrate the future results obtained.


All the data obtained is stored in the Health application and also in the internal history of the application. At the bottom you will find a tab called ‘History’, where you can view all the data obtained on a particular day. The display is very similar to the one we have in the Apple Watch in the Activity application. You can see how in each day there is a series of three more or less complete rings to know which day you have slept worse or better. Simply by clicking on one of the rings you can access the entire detailed history of that night.

Just above the calendar you will see a bar graph where you can represent the parameter you want. From the overall design score to the amount of time deep. This is another very visual way of being able to see in a given month how well or badly you have slept. Every day you can accompany them with a series of notes to be able to pick up what you have done before sleeping, such as working late, having a stressful situation or even drinking too much. All these parameters can also influence to outline a clinical judgment about a sleep problem in relation to an external factor. And of course, at the top right you will find the possibility to export all these data in .csv format to send them to whomever you see fit.

Automatic sleep detection

This application stands out because you have to click anywhere to start the dream. It automatically detects when you go to sleep and also when you wake up. But if you don’t trust everything in this system, you can click on the ‘lights out’ button in the Apple Watch. From that moment on it will start counting the time until you fall asleep, which is called the preparatory phase. This is where the detection of the final result may fail a little bit when doing it automatically, since it will depend on the amount of tossing and turning in the bed at the beginning.

But not everything is positive, because added to these small calibration errors we can miss some functions. One of these is the recording of sounds during the night. This can be interesting to detect if you are talking in your sleep to know what you can say. This is something that exists in other similar applications but is not present in AutoSleep.
