This is a great great app for staying on track with the HCG diet. Ive done this diet several times and "know" how it goes, but this app has really helped with identifying what is OK and what isnt. Im seeing much better results this time around then previously and I really think it is due to being able to track my food, weight, doses, glucose, exercise, etc all in one place. I think the fact that it also offers phase 3 and 4 tracking will also help with continuing the process in the long run, which is key with this program. There are some things that could be "better" from a GUI perspective but everything you need is right here.
