56.
I have 56 apps installed on my phone. I have just counted them. Even I, someone who is convinced that apps are dying and has intimate knowledge of the concept of app fatigue, am surprised at how high that number is.
In 2015, a data research company called Millard Brown Digital surveyed US smartphone owners on their app usage. They have found 43 percent of them use four to six apps per day on average, out of the average 40 to 70 apps they have installed.
