Plenty of apps can track your weight. FatWatch will analyze it.
You cannot control your weight if you aren't aware of how it is changing. Beyond recording the readings from your scale, FatWatch computes a moving average so that you can see the real trends behind the day-to-day shifts in your body weight.
FatWatch estimates how much energy you are burning (or overeating) each day, giving you valuable information you can use to intelligently adjust your diet and exercise plans. It only needs your weight: there is no need to fuss with a food database every time you eat something.
If you've already been tracking your weight, FatWatch allows you to import weight history from a variety of sources, including Eat Watch for Palm. You can also export to your Mac or PC and do with it as you please. No additional software is required.
