Accessing your favorite social nets on iPhone is currently a less than amazing experience, mainly because of the need to switch between networks, mapping, and contact information (it's enough to make a person frantic). But if the Paris company Never Alone Anymore has its way, the new HiMyTribe app will serve as the location-based people finder of choice. It uses the iPhone and iPod Touch's GPS capabilities to help people manage their groups (or professional and personal "tribes") and identify people they would want to meet who are in their vicinity. A criteria-based search engine helps you locate people with similar interests, including business travelers, friends of friends, conference goers"”even potential dates. (Imagine looking for a well-qualified designer who can meet you for espresso in Zurich on the fly.) There is a "blacklist" option, and exact locations aren't shown until the other user accepts. The free app, which the company describes as the "first truly real-time person to person application for the iPhone," allows for 20 tribe members globally, or there's a larger network option with a monthly fee.
