I just find out this App and i know it will really help you so much in sharing your installed apps on your Android devices with your friend.
As we all know that sharing of installed apps in Android is one of the great happiness, remembered me those days of Symbian OS. This one is not through WIFI as Flashshare does but through Bluetooth

An app made it easy for us to share apps via bluetooth and not only installed app but also system app too



The app am talking about is Bluetooth App Share
