This app really helps me keep conscious on the portions I eat. While I know what to eat I always have problems with portions, as well as keeping track of what I am eating while Im out. I dont use this as a bible but more of a basic guideline. It also connects right up to my scale and keeps super accurate update and I can see how much Ive lost. Only downside is advertising but hey they gotta pay for their product somehow :)
