The iCarbs app provides information about foods and how they are rated for carbohydrate content. This is provided as a means to assist in deciding which foods to eat. If you are a bodybuilder, you probably want to have a high intake of carbohydrates, but on the other hand if you have diabetes you need to make sure you don’t exceed your recommended daily amount of carbohydrates. The foods are rated from EXTREMELY LOW in Carbohydrates all the way up to EXTREMELY HIGH.
