Suddenly you find yourself with some extra time on your hands and
your spouse, child, or parent tells you about a great app. If this
person is a member of your household, they can share the app with you
via iTunes sharing. However, what if you are on the road with your
spouse or children and want to try out one of their apps, or share one
of your own? Apple provides an easy way to do this.Apple allows you to download an app you’ve already purchased from the App Store. This is perfect for when you purchase an app and realize the app isn’t synced to the iPhone. Simply “repurchase” your app and Apple will let you know that you already purchased it and there won’t be any charge. Thus you can reinstall any app you already purchased while on the road without any need to re-sync. Essentially you share apps over the air between your device and your synced iTunes.
