It seems like every time I turn around, there's a cool new app out for iPhone. Go ahead, turn around -- there's a brand new one out now that you just might love, and, for a limited time, it's free!

iSPINNING tracks your heart rate as well as other cardio and cycling data, such as speed and cadence, so you can use it both in a spinning class or on the road or trail. Right now, you can download it for free by logging into the App Store from an iPhone or iPod Touch and searching under the Healthcare & Fitness category. You'll be able to checkout how it works before committing, although, since it's free, what's there to lose?

This new application is perfect for spinning fanatics as well as anyone interested in trying out the newest fitness technology. Give it a go and let us know how you liked it in the comments!
