There are 2.3 million iPhone users in the United States. Are you one of them? If so, make your iPhone work a little harder for you: According to Woman's Day magazine, 869 of the more than 1,700 applications available to iPhone users from iTunes are health related. Losing weight? Getting fit? Trying to eat right? There's an application out there for you and your iPhone.

To save you time, Woman's Day did the legwork for you. They went out and found the 10 best diet and fitness iPhone applications in the iTunes store. Here are some of my favorites:

iWatchr: If you've ever tried Weight Watchers, then you know all about counting points. Rather than carrying that little slide-y scale WW gives you, download iWatchr. Look up point values and keep track of them all in one handy place.

We're all about affordable fitness here. That's why we led you to Jackie at "Love and Blueberries" for her five inexpensive fitness finds. Now, we're heading you to Kristen at "CafeMom" for a little lesson on using your iPhone to whip that bod into shape.

OK, so iPhones aren't exactly a low-budge item, but the applications are, and even if you don't have the phone, you can use the same tools online. If you're sweet on daily calorie counters, food information databases and calories burned calculators, go see Kristen for the skinny on cheap stuff.

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!
