Google Maps racked up its 5 billionth install in March of 2019.

The app is one of several that come standard with Google Mobile Services which most Android device makers have elected to implement. Where it does not come standard, such as on Amazon's Fire tablets, it's a very popular mapping client to reinstall along with GMS.

As for which app could be next on the eleven-digit watch, Google search is a strong possibility.
