How many Android users are there in the world?

Android has great number of users on its platform, with numbers reaching up to 1.4 billion.

While iOS has about 505 million users.

Are there more Android or Apple users?

There are essentially two viable smartphone operating systems, Apple’s iOS and Google’s Android. However, since Android has a much larger install base and sells more smartphones each year, it actually loses more to Apple than it gets from iOS. (Note that I own Apple shares).
