Xender app is a file sharing app for android it use wifi instead of bluetooth to transfer your files like PHOTOS, APK, DOCS, VIDEOS and any other stuff. Using wifi it create a wifi hotspot on one of the mobile betwwen the tranfer will be done another one conects that hotspot and take files at very fast rate it gives me around 5 to 10 mbs speed which have more fast then bluetooth.
It helps me to save lot off time that I was wasting when I was using bluetooth or tranfer of files.in todays date every andriod user must have this app in there smartphones
