Edit: Since there are always questions, I wanted to add it here.
# The APP supports Screen Mirror. So screen mirrors
Unlike many other apps that only support media streaming, ie stream photos, music or videos from your phone or tablet to a device, the presented APP supports complete ScreenMirroring, so no matter what on your transmitter (phone / tablet) screen is just, is installed on the recipient on the AirPlay / DLNA receivers (eg FireTV, another phone or tablet) is transmitted.
# Volume / Volume
The volume is so controlled the phone directly via the transmitter.
# Video Play
also here is the video, such as Youtube, which is mirrored to the receiver (eg FireTV), via mobile phone / Tablet (transmitter) as play, pause, volume, etc ... controlled.
# For iOS Devices
Has been following the AirPlay / DLNA receiver installed, for example, select on a FireTV, just at a iPhone or iPad on the Airplay function the recipient as FireTV (highly wipe Select from the bottom of the screen, AirPlay). Here you can choose then whether only audio, or audio and video to be transmitted.
# With Andriod Devices
Here I am not so sure as the state of development looks like. I think the Lollipop Screen Mirror natively supported as a transmitter. But sooner you needed a transmitter on the Andriod APP, eg "DLNA / UPnP TV channels" or "AllCast". After the installation select the device, on the AirPlay / DLNA receiver installed, eg FireTV.
# It can be games from Mobile Stream on the FireTV, just like music from your phone playlist, videos from YouTube etc ... eg
