Orbit™ social phonebook is a iPhone app that provides a smarter way to communicate via your mobile device so that you stay "in the know" about what matters. Orbit, built with the vision of simplicity and ease, was born out of a need for more control of your communications. The founders of Orbit are mobile and Internet experts with consumer experience across social media, search and messaging applications. They joined forces to create the first cross-platform, cross-network, cross-device mobile social phonebook that cleverly organizes all of your communication channels: voice, text, e-mail and social networking. The “Inner Orbits” option and “Social Volume” control enable you to group friends into orbits and decide how often and how much you hear from them. You have the power to control the volume of your orbits – keeping things quiet or turning up the volume for real-time notification.
