Xender is a free Android tool that has the sole purpose of allowing users to transfer files back and forth on multiple devices. Keep in mind that this application does not use technologies such as Wi-Fi, Bluetooth, or mobile data connections. It works by using the NFC (Near-field communication) protocol, and it requires that all devices involved in the file-sharing to be close together.
Xender comes with a well organized and designed user interface which everybody will find it easy to use. The NFC transfers are way faster than Bluetooth, for example, and there aren't costs involved. The actual transfer engine allows users to send data such as regular files, music, videos, contacts, applications, etc. To get everything working correctly, you must create a Group, and all devices must be close to each other.
Once the pairing takes place, your device is ready for sending and receiving files. All smartphones and tablets involved in this transaction must have the application installed, allowing you to perform file transfers from Android to iOS and vice-versa with no problems. As a bottom line, Xender is indeed a useful piece of software that lets you transfer files back and forth at faster speeds than Bluetooth.
