AirDrop is a Wi-Fi ad-hoc service in Apple’s OS X operating system, introduced in version Mac OS X 10.7 Lion. Using AirDrop, users can share files with other supported Mac computers running OS X 10.7 or later without the need of a Wi-Fi network or any configuration and without the need of USB mass-storage devices.
Now, Instashare brings the same technology to iOS devices, allowing you to easily share files between iOS devices and Macs with a simple drag-and-drop ( Android and Windows support coming soon ) .
