It provides an iPad simulator that aims to help you get accustomed to the look and feel of an iOS device. IPadian is designed to transform your Windows computer into a device that supports running apps specifically created for iOS. However, you can still download and use the last released freeware version from Softpedia. This means that you have to purchase the full product to be able to use it.
Note: The newest edition of iPadian is no longer freeware but commercialware (no free trial or demo).
