SimArchive makes it easy to distribute iOS Simulator builds of your apps. It lets you import and export apps from iOS Simulator devices, including their respective Documents/Library/Caches directories. Just select the right iOS version and the device the app is (or should be) installed in. SimArchive then shows you a list of all the apps currently present on the device and lets you export or import them with one click. Exported apps can be distributed and installed on other machines, used as snapshot of the current app state or deployed to other Simulator devices on the same machine.
Requirements: SimArchive requires at least OS X 10.9 (Mavericks) and Xcode 6.0.
