Easy Share is an app for transferring files between Android devices, using the Wi-Fi connection instead of a mobile data connection. It is designed to be used without data, and works even if the devices have no Internet connection. The transfer is done in a secure, confidential, and fast manner, with no need to create accounts or log in, and it is free forever.
The transfer is done by using a technique called Wi-Fi Direct, which allows you to connect to a Wi-Fi network without having to use your mobile data. With this app, you can connect to a Wi-Fi network and transfer files to and from your phone.
