The end of the year has arrived, and as usual Apple has released the top iPhone apps of 2014. Three categories include the most downloaded free apps, top paid apps, and the highest grossing apps of the past 12 months. Top billing in the free app list goes to Facebook Messenger, which separated messaging functionality from the main Facebook app. Both YouTube and Google Maps, which used to come pre-installed in earlier versions of iOS, also made the top 10 free apps.

The game Heads Up! beat out Minecraft - Pocket Edition for the top slot in paid apps. Cut the Rope 2 followed up on its predecessor with a showing in the top 10 as well. Finally, the top grossing category was lead by Clash of Clans. Like Clash of Clans, other popular titles such as Candy Crush Saga and Farm Heroes Saga are free, but made the top grossing list thanks to in-app purchases. Here are the top 10 iPhone apps in each category:
