I have been using this app for 2 months and I love it for tracking and keeping me motivated to hit those milestones! Its nice to see a chart of where you have been, where you are now, and where (hopefully) you will be going in your weight loss. I push myself to make those weights by the dates it lists because I committed to losing those #s per week.
Plus, if you fall off track it doesnt beat you up either! I would recommend it to anyone serious about losing weight
