A cross cross-platform app that will allow users to share screens among phones/tablets. You can share your phone screen with a friend over wifi. Additionally, you would be able to control and give inputs to the screen (like remote assist).
This remote assist app would work across iOS and Android. This great for helping our elderly parents and those who are not as tech-savvy become more comfortable with the digital age. Additionally, screen-sharing sessions be can recorded for later reference in case our parents keep asking the same questions again.
Other features could include in-app tutorials and custom annotations where you walk your potential through the features and functionality of an app.
