Hydracoach calculates the amount of water you need to drink each day based on your weight. As you drink, it lets you know how much is left for that day to lose weight. (not for the losing weight part, but I need to drink more water)
Ah the floppy disk and cassette. Sad thing is, I don't think we have any computers left that would take a floppy disk. However, I do have stereos that will take cassettes. And yes, I proudly can say I still have some cassettes.
