Oovoo is a online social video messaging service, available to download and use on Macs, PCs and iPhones. Oovoo was first released onto Microsoft Windows in 2007. It is similar in some ways to the Skype service.
Oovoo currently has over 75 million users, and is popular with the teen and young adult demographic. The OoVoo video chat and messaging app enables the user to video chat with up to 12 people at a time and you can see up to four people at once on screen.Oovoo can also be used for business purposes, with conferencing software allowing phone and video calls from up to 12 different locations.
Oovoo Is Free to Download and Use
The service, as with many other free services, makes its money from advertising, but paying for the 'Premium' oovoo account stops adverts from appearing.
OoVoo also has integration features not available on the similar Skype app. Built-in tools allow users to record a video chat and then upload it to YouTube. In addition, Oovoo also offers a way for a person in a video chat to choose a YouTube video and show it to other users as part of the video chat.
