Fallen Earth's new app lets you chat with players, browse the auction house and view the map.

Not to be outdone by World of Warcraft mobile application, Fallen Earth has released their own companion app for the iPhone, Android, and Blackberry (for those who want to traverse the wasteland on company time.) The features will keep you in contact with a Fallen Earth server and give you access to a variety of in-game functions:

View Crafting: View available recipes and check progress of those currently active.
Visit the Auction House: Browse items up for bid and keep tabs on your own auctions.
Check Your In-Game Mailbox: View incoming and received messages.
Access Achievements: View all acquired achievements, those in progress and your current score.
View Online Friends: View clan mates or friends lists to see who is online and socialize with other players.
Chat with Other Online Players: Chat in several different channels, such as Help, Clan and Faction.
Examine Characters and Stats: Switch between characters and view your currently equipped gear, stats, pack, and weapons.
Access the World Map: Open a full overview map of each of the three Sectors and newly opened area of Deadfall.

The main difference between Fallen Earth's mobile app and WoW's is that Fallen Earth's costs 1.99 on iPhone and Android and 2.99 on the Blackberry. WoW's is free but it doesn't let you communicate with online players, unless you subscribe to the World of Warcraft Remote Service and pay 2.99 a month. If you choose to subscribe, you can buy and sell on the WoW auction house from anywhere.
