I will gladly credit my Fitbit Aria scale for the same result.

Interestingly, it is less for the feedback if gives me in the short term and rather the long-term graphs. I know that if I want to manipulate the scale up or down in weight and fat percentage, I have to be consistent over really long periods of time. I almost never miss days running or at the gym, my days of heavy drinking are long behind me, and I feel orders of magnitude better than I have in years past. These systems really are fantastic tools, and show that the application of game mechanics can be a force for enacting strong positive change on a personal level.
