A Call of Duty companion app is now available on iOS and Android devices, Activision announced today.

The free app tracks stats across Call of Duty: Black Ops 4’s three main modes — Blackout, Zombies, and multiplayer — as well as Call of Duty: WWII’s multiplayer mode, according to a post on the Activision Games Blog.

The app provides players with weekly reports on their performance and follow-up briefings with “personalized” tips for improvement. It will even allow players to track “every bullet and movement” in a given match, so you can analyze previous play sessions.

Call of Duty Companion App also allows you to track friends’ stats and create squads with up to 20 other players. Squads will then be able to earn in-game rewards by collectively completing weekly objectives. Activision also teased potential real-world rewards from “partners such as KontrolFreek,” the popular controller accessories company.

Activision’s Monte Lutz added the publisher will “continue to add new capabilities, including localization, a loadout editor and chat” at some point in the future.

In other Call of Duty news, fans are upset with, but not surprised by, Activision’s recent rollout of microtransactions in Black Ops 4.
