How many apps do you have installed on your smartphone or tablet? If we had to guess, that number would be fairly large. I have just over 70 installed on my Galaxy S III, however I would probably say that number is on the lower end as compared to some. Needless to say, regardless of how many apps you have personally, one thing is clear -- apps are popular. And in fact, with more and more users moving to smartphones, the amount of downloaded apps is only going to increase.
