iTunes "Lose It" - App - amazing

I put this app on my phone and it works like a charm-excellent. I just set my goals and add the calories per day, it tells me how many more I can have for that day-and you can add in excercise-amazing. I know weight watchers counts calories/points, but this way I have total control.
I have already lost 2 lbs in 10 days, my goal is to lose that annoyng 7-10lbs. And, I am not starving.
You can use it online and do group stuff as well.
Try it!
