Here are three great Android apps to enjoy. Sonar: Friends Nearby emerged out of beta last week, so we’re glad to see it available for everyone to enjoy. It helps you connect with like-minded folks close by. GrooveRunner is a fitness app that includes the ability to track your training, play your music and share your progress with friends. Finally, we’ve got To-Fu 2, a fun and stretchy sequel to blockbuster hit To-Fu: The Trials of Chi.
