Retty is a free lifestyle Android app developed by Retty.Inc. It is a social network for foodies to share their favorite restaurants with friends, follow trusted users, and discover new "favorite" restaurants. Members sign up using their Facebook ID, so everyone is vetted and secure.

The app allows users to post about their favorite restaurants, follow like-minded foodies, and create their own customized "MyList". The higher the rank, the greater the visibility. The network of foodies means reviews can be trusted, and the app is regularly audited to weed out unfair reviews.
