I have been using this app to transfer apps from friends mobile from the day I have buyed my phone it is the first app which I downloaded from google playstore it is simply evolution of bluetooth it helps in transfer large files in very very less time and transfer files are not modified as if we transfer any pic through whatsapp its pixel changes which in turn changes the picture quality but through share it does not happen share it ensures perfect quality of picture that is transferred so share it is a very very useful app that should be present in everyones mobile
