Do not "join" a crowd, simply track yourself. Every day this app tells you precisely what else you need for sustenance and activity to have the right nutrient, calorie, mineral, water, fat, carb, protein (and more) for your personal goal and it shows you in the tabulated list as you go through your day. I was so amazed. It takes the UPC code you photograph right off your package of whatever food you eat and then adds all the FDA required info from the ingredients to your micro and macro totals in the exact portion you specify. No more guessing - just the facts! So it works. No hidden fees, thank you, its healthy and scientific, and straight so that you want to be straight with it too. I honestly Respect this app. And hope to use it until I learn all the foods and nutrition I need to live a good life, so I may be using it - at least as my dictionary- forever. Hurray for easy, truthful, and well thought out information. The best app for an intelligent person.
