I used it for a while and I would reccomend other people try it but only for a few weeks to actually see on paper what they are eating and what they can fix. As for calorie counting on it it's too vague to be of any use. The amounts could be off just a little and that throws off everything so ignore that part. It's just a shock to see what you actually ate throughout the day all on one list. Same goes for the excercise ignore the numbers. Too vague to change anything for results.
