Twitter, Facebook, and the like are all decent ways to stay in touch with people you already know about, but Roamz has solved a problem you might not have known you had. What happens when you're traveling? What if there are time-sensitive events happening near you, but you don't follow those related social networking accounts?
Roamz is an iPhone app that learns your interests, and thanks to location-aware technology, suggests news and activities that might appeal to you. It works pretty well! You can tell Roamz what type of items you are interested in, such as kids' activities, dining, shopping and more.
The app takes advantage of the iPhone, thanks to GPS, but I'd like to see an iPad version so there would be less scrolling. Roamz is especially nice when traveling because you don't have to know who to follow and you don't have to follow them permanently (or unfollow them when you've returned home).
