Really easy.

Started tracking my calories for weight loss. Only wish I could set my target calorie intake to 1,500. I haven’t figured how to yet.

Other than that, I love it. I’ve only started using it for a few days. Once I use it more, I will write another review.

My initial review is solely based on how user friendly it is.
