The mobile port of Capcom's latest fighting game will be compatible with iOS 5 devices or higher, which means that it will run on the iPhone 4 and 4S, iPod touch 4th Gen or later, iPad 2 and the new iPad.
The iOS version adds new game modes, and offers what is described as a "new take on the tag-team mechanic".
The controls will be redesigned to better support mobile devices, and Capcom has altered the user interface.
The balanced character roster features fighters such as Chun-Li and Ryu from Street Fighter and Kazuya and Nina from Tekken.
It will launch on iOS devices this summer.
The console versions of Street Fighter X Tekken were released in March.
Producer Yoshinori Ono fell ill during the Asian leg of its promotional tour. Ono has since criticised Capcom for overworking employees.
