Location-based travel network, Dopplr, has finally launched an application for the iPhone. Dopplr enables users to share travel plans with their private network, find and recommend places to eat, stay and check out, and find fellow travelers that are nearby. Collectively Dopplr aggregates all of this information into what it calls the Social Atlas. The company plans to launch Dopplr for other mobile platforms including Android, Blackberry and Nokia by the end of 2009.
You can grab Dopplr for the iPhone from the App Store here.
