A simple service created by Kevin Morrill, textWeight holds you to your New Year’s weight loss vows by sending you a reminder text at 8am every morning, to which you reply (on the honor system) with your weight. textWeight then creates a graph of your weight loss progress, so you can measure every pound lost towards your goal over time.

I’m going to start using this. I actually use MyNetDiary to track my diet. And I use Google Docs / Excel to track my weight.
Perhaps TextWeight will help make it easier to track my weight.
Having the data in Excel is valuable though because I can do secondary number crunching.
