I have an iPhone 4!

I bit the bullet, forked over the cash and joined the rest of the world. Or at least some of the world—I got an iPhone today. It's not the latest, just an 8G iPhone 4. I didn't need or want all the bells and whistles, just some of them.

My husband thinks I'm obsessed...or will be obsessed, and he's somewhat fearful that he's going to lose me to it. But I swear to him that it won't happen. I get annoyed when people interact with their iPhones more than they interact with the flesh and blood sitting in front of them, but I appreciate the connectivity that such a phone creates. To manage the best of both, that's my goal.

Another goal? To download some cool health and fitness apps.

Question: What health and fitness apps do you use? Suggestions, please!
