Sensor Tower, an app market intelligence platform, released its quarterly report on Apple's App Store on Tuesday.
The report is chock full of interesting nuggets, but one thing is abundantly clear: Facebook owns your iPhone.
Four of the five most-downloaded apps in the world during the last three months of 2015 are owned by Facebook:
Messenger, WhatsApp, Instagram, and, of course, Facebook's main app, are all owned by Facebook.
Facebook's strategy to branch beyond the traditional Facebook News Feed and own other parts of the time you spend on your phone seems to be working. That's why it dropped a whopping $22 billion on the messaging app WhatsApp in 2014, and $1 billion on Instagram in 2012.
Apart from Messenger, which the company made mandatory if you wanted to message people through Facebook's mobile app, Facebook hasn't seen much success in developing its own apps.
And Messenger is becoming much more than just a messaging app. You can use it to send money, make video calls, order an Uber, and get customer service from some companies.
