Ever heard of WiFi Direct? Native to many recent Android devices such as those of the Nexus, Xperia, and Galaxy families, WiFi Direct allow users to essential transfer files between WiFi enabled devices, in a manner similar to how many use Bluetooth file transfer.

XDA Forum Member FD_ introduced to us an app developed specifically to emulate WiFi Direct's function, called Fast File Transfer. Available for all WiFi hotspot-enabled Android devices, Fast File Transfer offers to be a preferable Bluetooth replacement, boasting data transfer speeds of up to 20 times faster than standard Bluetooth, or more than 32 Megabytes-Per-Second which equates to 1 Gigabyte in under 5 minutes.

Once installed, Fast File Transfer adds an option to the 'Share' intent called Fast File Transfer. When Fast File Transfer is selected, a WiFi hotspot is activated, along with a web address or QR code that the receiving device then scans, prompting the download. The great thing about this transfer method is that Android devices can now connect to iOS devices, which such short-range transfers were not possible thanks to Apple's decision to not allow any non-iOS devices to connect to their products via Bluetooth. The use of WiFi tethering function of Android phones also means that devices do not have to be connected to one, pre-existing Wi-Fi network. Therefore, no bandwidth is used, and and no additional strain is placed on your Internet connection.

Available for free to all users running Android 2.3 or newer, Fast File Transfer is well-developed and simple app for fast file transfers. More details can be found in the original thread.
