Here is another app that really keeps me on my toes! It is called "Water Your Body" and it is $0.99! I have noticed a big difference in controlling my appetite just by staying hydrated.
This app really motivates me because if I drink all my water for the day I get an "A"! If you get 7 "A" days you get a bronze trophy, 30 days a silver, 90 days gold and 365 "A" days you get platinum. Like I said before....I respond well to gimmicks!
