Sprouter, the well-known social networking service for entrepreneurs has released an application for iPhone and iPod touch users. The Sprouter app provides a native interface for Sprouter members to connect with other startup founders around the world for networking, collaboration and knowledge-sharing. The app includes all of the functionality from the Sprouter website including the ability to post updates, access pre-defined and custom filters, view replies, send and receive private messages, star posts, view and RSVP to events, and search the service. Users can also seamlessly switch back and forth between the iOS application and the Sprouter website to follow feeds and events on whichever platform is most convenient. Sprouter is available from the App Store as a free download. A free Sprouter membership is required; users can sign up from within the app.
