Infinity Blade II
Long one of iOS's most popular gaming franchises, Infinity Blade II is now free for a limited time. The app also received a minor update.
New in version 1.3.2 are a number of expansion packs, including Clashmob, Vault of Tears, and Sky Cages. It also supports full-resolution play on iPhone 5, iPad 4th generation, and iPad mini and is fully compatible with iOS 7.
Infinity Blade II version 1.3.2 is available now as a free, 1.10-gigabyte download from the App Store.
PDF Expert 5
PDF Expert 5 has gone universal in version 5.1.1, supporting both the iPad and iPhone with a single purchase. The company has also made a number of changes to the user experience, including a speed bump that they say is "blazingly fast."
In addition, vertical PDF documents can now be scrolled continuously, rather than requiring paging. Calculations in LiveCycle Designer forms also work properly, allowing PDFs that include spreadsheet-like functions to be fully utilized on iOS.
PDF Expert 5 version 5.1.1 is available now as a $9.99, 61.7-megabyte download from the App Store.
