RunKeeper, the popular running, walking, and cycling tracking app for iPhone, has gotten even better recently with a whole new design, and funner, easier to use experience. And since it's Mobile Nations Fitness Month, the time couldn't be better to give it another look!

Thanks to last month's update, you can now add a photo showing your complete exercise activity, and share it with your friends. You can also share goals to Twitter and Facebook, and can even broadcast your activities live from the RunKeeper Start screen. Live broadcasting requires RunKeeper Elite, however, but you can now sign up with RunKeeper Elite right from within the RunKeeper app.

If you haven’t used the RunKeeper app before, it is certainly worth checking out. It's a free download, so you have nothing to lose, and since it lets you track your runs, walks, bike rides, hikes, and more using the GPS in your iPhone, it can fit itself to any number of activities. RunKeeper Elite, their subscription service, costs $4.99 a month or $19.99 a year. You don't need it to use RunKeeper for iPhone, but if you're really into RunKeeper, it offers some nice extras, like the aforementioned live streaming.

If you are looking for an app to help you get fit in 2013, you should really check out the new improved version of RunKeeper. I put on quite a few pounds over the holiday period so I have RunKeeper all set and ready to go. Hopefully I will be able to burn off those unwanted pounds sooner rather than later; I bet that losing them is nowhere near as much fun as gaining them!

Give it a try and let me know what you think!
