A free app for Android, by Foursquare.

Marsbot is a new way to discover new places and get great recommendations from local experts. The app uses a combination of AI and human intelligence to learn about your habits and preferences and then provides you with great recommendations. You can set your preferences and tell Marsbot where you go every day. It will then use your information to recommend places to you based on what you like and how you spend your time.

In addition to helping you discover new places, Marsbot can also help you keep up with local events. It will send you a notification when there are new events nearby that you might like to attend.
