So you’ve gathered all that sleep data – what do you do with it? Sleep as Android offers you easily readable reports for the quality of your sleep. Read about them in this chapter.
Where to find them
- Adding tags
Analysing tagged sleep
- if +-15% from the average the coloring is green
- for any unusual values out of the average we use red.
Values above the average may mean some error of measurement – for example the phone was not close enough to the body. Values under average may indicate too much light sleep due to various factors such as stress, alcohol consumption, loud environment etc…
- Custom tags
- Frequency tracking
- Location tagging – geo tags
Charts provide more insight into Your sleep data and put them into perspective.
You can filter your data by period (Week, 14 days, Month, Quarter, Half year, All), by days (Workdays, Weekend) and by tags. We recommend to use longer period rather than short in order to get statistically significant data into your charts.
This line chart shows you the evolution of your sleep lengths. On the left, the chart starts with a date you set with the bottom dropdown menu and then it goes all to way to the right, which is today.
The green line shows you how your whole sleep length has been changing, while the dark blue line shows only how your deep sleep length has been changing.The light blue lines are averages (one for whole sleep length, one for deep sleep length).For example, in the chart below, you can see how my sleep was oscillating, but the average is still around 7 hours. You can observe a drop in deep sleep length on 3rd February.
How should it look? Ideally the chart should not have many extremes (regular, periodic chart is normal) and on the average, deep sleep should be ca half of whole sleep duration.
This chart is a useful chart for tracking Your sleep deficit. There are two lines.
The green line shows the deficit on a given day. If You sleep less then Your ideal sleep time, this line will be negative on that day. If You sleep more, it will be positive.The red line on the other hand shows the total deficit. Every day’s deficit gets added to the deficit pool, so You can see here, how big the actual sleep debt was. This value is what You have probably felt the most – whether You were refreshed or totally exhausted.
How should it look? You should strive to have zero sleep deficit, so ideally both lines, green and red, should be very close to 0 hours all the time.
This chart presents another view on Your normal sleep records. You can observe Your sleep patterns here, i.e. at what time do You go to sleep usually, at what time do You wake up and if You choose short enough period (e.g. a month), You can inquire into Your light sleep/deep sleep patterns.Green parts are light sleep.Dark blue parts are deep sleep.
On this tab, You can see the evolution of Your sleep characteristics all in one place.
Deep sleep % chart
This chart shows You how Your deep sleep has been changing recently – effectively how well did You sleep.
How should it look? The average should be kept around 50% (+- 15%). Ideally every day, You should have a 50% deep sleep on a normal sleep pattern (i.e. sleeping 7 hours/day).
Here You can see the evolution of Your snoring time per night. If You want to see what has an effect on Your snoring, use the tags everyday and then look at the Tags charts tab.
How should it look? There is no single answer – e.g. if you wake up people around you, it may be time to start worrying about the percentage. However to snore a little is perfectly normal. So this is up to you and your surroundings.
You can see the history of how did you rate Your sleep in the selected period.
How should it look? If you don’t rate your sleep at all, this will be zero. Otherwise, you will see a jagged line.
Fall asleep hour chart
You can compare the times at which you have been going to sleep recently in this chart.
How should it look? It depends, but generally abrupt changes in the time at which one falls asleep may have a negative impact on the body and energy levels.
Smart wake up chart
This chart shows how many minutes before your set alarm have you been waking up (while using the smart wakeup feature). This interesting measure visualized in charts is wake up before scheduled alarm time, which basically tracks what difference smart wake up does for you and whether your body is accommodating to smart wake up or not. This stems from an interesting theory that your body is able to adapt to the smart wake up feature over time and pretend that you are in deep sleep (not moving) before the alarm to increase sleep time.
In general, these charts connect the tags with sleep characteristics. You can e.g. track whether sport has some effect on your deep sleep percentage, whether you snore more after alcohol and gain other useful insight. You have to use tags of course in order to benefit from these charts.

Snoring chart based on tags
Chronotype is a term used to characterise your sleep patterns. It is a spectrum ranging from 100% night owl to 100% morning lark. Read our introduction article.
Your currently detected chronotype will be always shown in the left menu. This one is detected from the last half year of sleep data.Sleep irregularity chart shows how stable your fall asleep hour, wakeup hour and sleep duration is. Most regular sleeper would have a horizontal line from left to right. The irregularity shown is the variance of your mid sleep hour.
The chronotype trend chart shows the evolution of your owliness/larkiness. This chart always shows all-time data since shorter period do not have much meaning to the trend.
The chronotype value (mid sleep hour) is computed from weekend or “weekend-like” days to get the natural chronotype (see http://sleep.urbandroid.org/documentation/extended-features/chronotype/).
The mid sleep hour chart shows the average middle hour of your sleep records. This is a good indicator of your general tendency towards being a night owl or morning lark.
The social jet lag chart shows how your sleep pattern differs on workdays and on weekdays. We actually do not use the normal definition of workdays and weekdays, but compute “work-like days” and “weekend-like days” from your historical data.
If you don’t know how could you make your sleep better, go for some advice to this tab. Sleep as Android gives you evidence-based advice along with supportive charts. Of course such advice needs to be taken relaxed and used only as a slight guidance in which direction you may want adjust your sleep habits. But we don’t recommend to do any dramatic changes to your sleep. Our recommendation is gradual iterative adjustment with feedback from the sleep tracking. Also the performed analysis always needs some correction and interpretation from the user side.
Advice regarding your social jet lag
Fall asleep hour – regression model
Here you get a variation on the Fall asleep hour chart with a twist. You can observe the influence that you fall asleep hour has on the quality of your sleep (deep sleep % and your subjective rating). Sophisticated methods are used in order to extract more useful data. You can see a regression model. This means that we have processed your data, filtered out any outliers (i.e. extreme values) and found a mathematic formula that best fits your data. On the basis of this formula, it is possible to statistically predict future behavior.
Duration – regression model
Similar case to the fall asleep regression model, you get a polynomial interleaving your filtered data. The data are presented in a way that you can see what influence has the duration of your sleep on its quality.
There are two weekday charts – on one you can see on what days in the week you sleep more, i.e. your sleep lasts longer. On the other, you can see on what weekdays you have better quality of sleep (better deep sleep %).
Fall asleep charts
There are three fall asleep charts in the Advice tab. You can see what effect your fall asleep hour has on sleep duration, deep sleep % and the amount of snoring.
