Ubisoft has launched a companion app for its most recent entry in the Assassin's Creed series, Assassin's Creed IV Black Flag. The app is available for download on both iOS and Android devices, giving gamers a more immersive experience in Edward Kenway's Caribbean adventure.

The second screen has many features including an Interactive World Map, which allows you to set waypoints when looking for treasure, and view your mission objectives in real-time; you can also get your friends to hop on board your journey as they take on the role of your quartermaster using the app.

Kenway's Fleet is a component designed for use when you're not playing the main game on your console. Ships captured in-game can be sent to Kenway's Fleet and then sent forth into battle, collect cargo and currency and complete additional missions.

All of your game's data including mission progress and current game status is stored on the Progress Tracker. Treasure maps found are stored in the app, allowing you to analyse them and determine where you've to travel next to find the hidden treasure.
