I came across that figure. The headline read that now that Android had 50K+ apps, they could be a serious challenge for the iPhone. It is impossible for a telephone to be that useful.
There are exactly 13 applications that make any reasonable sense for a handheld portable telephone and three of them have yet to be invented. Those three are telepresence, credit card and positive ID. The other ten are obvious because you already have them on your smartphone. The other umpdeumpthousand are inflation.
