I have seen so many sharing apps but this app is very good and fast. I sent so many videos and photos and even files and documents everything to my friends. This shareit works with hotspot. But when you send video or photo to your friend, it sends very well. but if there is anybody opens their wifi. It connects our internet very easily into their device. So be careful when you are doing such things. But this is one of the best app I have ever seen.
