The folks at FitnessKeeper, Inc. have pushed out a big update to the popular RunKeeper app, bringing a holo-like interface and a slew of new social features to help make staying healthy more fun. The biggest of these is the new Friends tab, which ranks buddies gathered from your contacts and Facebook by the number of activities completed. You can find these buddies without leaving the app, and even give them a gentle poke if they seem to be slacking using Android's in-app messaging service.

the rest of the changes are pretty darn good as well. The new holo look with tabs and action bar navigation is a welcome sight, there's a new activities page to help keep track of what you've done and what's coming up, and there's now a bit more flexibility when you sign up for a new training plan. 

To take advantage of these new features, you'll need to connect RunKeeper to your Facebook account. Since that often can be a security nightmare, there's plenty of information on how to do it safely at the source link. You can grab RunKeeper from the Google Play link above, and catch a few screenshots of the app after the break.
