That includes iPhones, iPads, Apple Watches and the rest of its current product lineup.
It's an Apple world after all.
The Cupertino, California, technology titan disclosed in a financial document that it has an active base of 1 billion devices in the market. That includes iPhones, iPads, Macs, iPods, Apple TVs and Apple Watches that the company said were engaged in its services over the past 90 days.
The staggering figure underscores the continued strength and influence of Apple, which has steadily expanded its portfolio of products. It also helps explain why developers flock to its app store, and why the company has seen growth in services such as Apple Pay and Apple Music.
"This is an unbelievable asset for us," Apple CEO Tim Cook said in a conference call with investors on Tuesday.
The figure comes after Apple posted a profit of $18.36 billion -- a record for any company -- but saw the growth in its iPhone sales hit a wall.
