EA has released the free Mass Effect 3 DataPad on the App Store for iPad and iPhone.
The App bundles the game's Codex - complete with voiceover - along with Mass Effect 3 cross-functionality, letting you receive updates from characters in-game, deploy your fleet in Galaxy of War (as long as you've signed into Origin) to improve your Readiness Rating.
There's also News updates and a media library for all the trailers and screens released so far for the title.
You can download the DataPad here.
