In order to share your screen, you must have minimum Android version 5.0 device (4.3 for joining). Inside the app, you will see, if your device is supported or not. You can share your device screen over a local wifi network (joining devices have to be in same network) or over the internet. When sharing over the internet, you have to link your Dropbox account (or create one), because video and audio data is sent by using your Dropbox account as the content server. You don't have to worry about your other Dropbox files, this app will create a new folder where it stores recorded video and audio files. Those files will be deleted later to free the space that app took temporarily. Your other personal files will be safe, this app will not touch them.
NB! You will get only limited use of screen share over internet with the free version.
To join screen share, select wifi or internet option from the main menu. Then your going to see a list of available screen sharing sessions. Select the one your friend or collegue created and wait for the host to start the session.
