The purpose of ScreenShare is to use your smartphone screen with the tablet. It is a fairly new application that is still in beta stage. The app contains two parts - SpringNet and SpringMail, which allows to the user to read his email and browse Internet via tablet. To run the application, both devices must be connected via Bluetooth or WiFi.
ScreenShare Software Development Kit (SDK) will be released at the end of the year, that will allow developers to adapt their applications in order to share user interfaces and content. Some applications that can benefit from ScreenShare are the apps for maps, GPS, interactive training, caller of phone numbers, writing emails, reading e-books etc.
If you travel and don't have a constant WiFi connection, the best way to connect your smartphone and tablet is via Bluetooth. The application collects only the content that needs to show to the tablet, so the user saves battery and the phone doesn't need to be connected to a charger. Also, the phone can be in conservation mode, and applications will be running on tablets and so will save battery. Once you are done with the parallel session, the user can instantly restore all things on the phone.
The app is available for free on Google Play Market.
