App Recommendation: BHF Tracker

It dawned on me that some of you might not be inclined to measure for the same reason I initially put it off: I kept losing my damn paper. Where did I measure? Am I making progress? It was pretty bad.
Then I found the BHF (body, health and fitness?) Tracker. It's great. Tracks weight in kilograms, stones, or pounds, body fat percentage, as well as measurements. There are also cool charts and a BMI calculator (if you're interested in that). Anyway, its a great free app that's easy to use and it even allows for multiple users.
