Used this app since it released the concept of the app is good which is transferring photos, apps, files, movies and videos using wifi.
The app transfers very fastly and can be used by anybody, parents or childrens.I always use this app for sharing movies.It runs @10mb per second.
But sometimes it irritates as says receiver is offline or sometimes transfer of file is very slow.
Another thing which irritates , it uses Bluetooth to transfer , after transfer Bluetooth will not turn off.
Though above 2 demerits I recommend you to use this app.
