Aviassin iCalcy is a calculator for Windows which imitates the iOS calculator on iPhone
iCalcy looks and acts exactly the same as the iPhone or iPod Touch calculator does, allowing you to perform all standard calculator operations. You can even rotate iCalcy into either portrait or landscape orientation, just like an iPhone.
All functions in portrait orientation are supported, as well as memory and sign capabilities. Not all scientific functions are currently supported (all the common ones are), but we are always updating, make sure you check out our labs for any unreleased updates!
