Apps: when we use it? Study reveals habits of the owners of Android devices

Android devices The researchers of the German DFKI research presented at the conference Mobile HCI 2011 in an article titled “Falling asleep with Angry Birds and Facebook and Kindle.” To do this, they used a data collection system to see which apps are used and when.


As data collection instrument used was a system called AppSensor who, by entering a code of 4100 users in mobile Android in this case, has been monitoring what applications were used, recording the precise location and timing of opening and closing all apps .

The information was transmitted to the research team, obviously in a completely anonymous.
The number of monitored applications amounted to 22’626 and the number of executions of the app reaches nearly 5 million over a period of more than 4 months.

Here are some of the results:

The average use of apps is about 1 hour a day and the average execution time of 71 seconds. Except during waking hours, where we use more time.

“Wake Up!”

Alarm AppSensor found the application has a peak of activation between 6 and 8 in the morning.

Types of applications used and times of the day:

during the day is definitely in the category Communication distinct advantage over the app dedicated to games like Angry Birds, which have a spike in use from 6 am to 9 am and close at midnight. During the morning news instead depopulates applications.

Social networks:

Facebook is used more between 20 and 23 with a peak at 22. Twitter has instead a more constant peak before lunch and before dinner.

The greatest impetus to conduct this study, according to the researchers, was to make the system more efficient in mobile app recommendation of implementing AppSensor, who would know now, the place where we are and apps that were previously used, then quickly be able to propose with probability app that we would like to use at that time.
