The new iPhone app LocalFave is not only very well designed, it's also a great innovation, combining geolocalization and social recommendations.
Imagine you are looking for a good restaurant and would prefer to have friends recommendations rather than Yelp reviews (from people you have nothing in common with) to help you choose a place you don't know yet.
LocalFave allows you to rate the restaurants you're going to, determine which one is your favorite one(s), and most importantly, share it with your friends, who will be able to see your reviews and fave places.
Give it a try and stop picking the wronf restaurant!
Available on the iTunes App Store now.
