What it does: This app is supposed to tell you how many calories you shed when you're doing the "horizontal hula." It's pretty simple: You place your iPhone on your bed, and a kind of earthquake-seismograph interface clocks your movement and the equivalent calories burned. If you must, you can even share your results on Facebook.
Here's the problem: I was supposed to review this app this week. I wanted to. BELIEVE ME. Unfortunately, my husband and I have been working opposite schedules AND our 4-year-old has been sick the last couple of days. It all adds up to a sex life about as exciting as a game of Candy Land. The only way I could test the thing was to bounce up and down on the couch while my sick baby watched a Disney marathon. According to the app, I burned 45 calories. Yeah, my sex life rocks.
Why it's better to go old-school: Realistically, if you place an iPhone on your bed, it's going to fling itself off and land on your floor -- no biggie if you have carpet, but not the best way to get an accurate reading.
Worth it? Shouldn't having sex be one of the times we can stop fretting about the baby weight?
