☀☀☀ ooVoo is a free video chat app, similar to Skype. The computer version allows screen sharing, so users can see what you are doing on your laptop. Journalists could use this application to communicate with sources or other journalists. Unlike Periscope, ooVoo does not broadcast live. One thing unique to ooVoo: it records video chats for upload to YouTube, making it easy to share the content with others. Overall, aside from Skype’s obvious popularity, the two apps are comparable in many ways.   Nisa Ayral
