Working in conjunction with the Blue Jeans video conferencing service, the Blue Jeans app lets users join multi-party video calls from iPhones and iPads. The cloud-based Blue Jeans video conferencing service works with most existing video conferencing systems (Polycom, Cisco, LifeSize TelePresence, Microsoft Lync, Skype, Google Video Chat, Jabber, and even standard audio) to create a unified video conferencing platform that allows users to keep using whatever they're already comfortable with. With a 3G and Wi-Fi capable app, Blue Jeans app users can join video calls from practically anywhere.
