I really love this app. Its simple and easy to use. The variety of how it helps you get to your next goal is wonderful. How it uses a moving average to diminish both intense losses and intense gains is good. It has really helped me to stay on track.
My only wish is that I could add notes on my daily weight entry, but it is definitely highly recommended by me :).
