Shareit as the name suggests this app helps in sharing and transfering files like songs, photos, apps, videos, movies, etc from one device to another may it be an android phone, ios or a windows phone.Its auiet similar to bluetooth but speedly transfers the files from one device to another at a good speed.This app doesnt require any net connection to work.Its an amazing alternative to blouetooth.I would suggest you to try it out once.M sure you will also like it!
