Take a look at the above chart prepared by Statistica. It shows the average app downloads in the top countries and the global average. An understanding of statistics means that there are a few countries at the top with large downloads, and the majority lie below the global average. The chart puts the global average at 26 apps. In simple terms, most smartphone users download less than 26 apps to their devices.
The global average also indicates that most users pay for less than 27% of the apps that they download. In other words, on the average, less than 6% of apps downloaded are paid for. The remaining 73% are free apps. In some regions, we can expect less than 5% paid downloads.
I have 46 apps on my Lumia. How many apps do you have installed on yours?
