The current number of mobile apps in use counting both the App Store and Google Play are over 7 million. With app development on the rise around the world, expect this number to rise very quickly.
While 7 million sounds really impressive, a ton of the apps are either redundant or clones. While App Store cleaning up efforts have removed thousands of applications from the App Store, Google Play seems to love exaggerating the numbers by keeping the clone apps and apps that haven’t been downloaded in ages.
The number will definitely rise, but a major contributor to it could be commercialized template or app generation services that allow people to click or clone apps with a single click. Until this issue is sorted out by all the stores the way Apple is addressing it, the 7 million number might not be a true representative of the real number of apps.
This is an interesting question.. Check out this info from Statista... It is dated, but relevant.
How many are used is a matter of perspective - defined by what you consider as 'usage'. Some apps are used daily - like social / collaboration apps. Some are used occasionally - less than once in a day / week / month. Spreading the limits to being used once in a year - I guess all the apps listed in the stores would be countable.
Curious: What is the average number of resident apps in a mobile device?
