The first installment of the Touch Panzer Campaigns has been released yesterday. It is available for Android-based devices right now, but we will likely see the iOS version out soon.
From the Google Play store description:
"Tunisia '43 is the first paid release in the Touch PzC series. You should install and play the original free release PzC: Panzer before installing this app as that will give you the chance to test the game engine on your device and become familiar with the interface.
This release includes 16 scenarios based on the PC Panzer Campaigns game of the same name. These scenarios allow you to play the part of the German commander during the battle against the AI commanding the Allies. The scenarios range from the initial fighting against the British, American, and French forces through the climatic battle of the Kasserine Pass as well as some hypothetical scenarios.
While this version of Panzer Campaigns will run on large-format Android phones, it is best on an Android tablet with screen size of 7 inches or more."
