I downloaded this free app out of curiosity. I was taking a gander at the Health & Fitness category in the App Store and saw 2Fat. I thought it would be a weight loss manager or something of that sort and might be suitable to review for iPhoneBuzz, but when I downloaded it, I was sorely disappointed.

Okay, so this app does exactly what it says it will do. You are presented with two scroll wheels: one for your weight and one for your waist size. After selecting both numbers, you are given your body fat percentage. Now, if you switch it over to the BMI setting (body mass index), you’re asked to enter your weight and height. Then, your BMI will be presented.

These are useful numbers if you’re interested in your health, want to lose weight or want to achieve a certain body fat percentage but don’t feel like doing the math to figure it all out.

However, that’s all this app does. And unless you’re super familiar with BMI or how much of a body fat percentage you should have, these numbers are useless to you until you can look them up. This app would be a whole lot better if there were a reference chart included that showed you exactly where you measured up. Without this sort of reference, the apps is essentially useless on the go, unless you can look up a BMI chart, too. But if you ask me, that takes the convenience right out of this thing.
