Healthy Diet & Grocery Food Scanner by ShopWell The Healthy Diet & Grocery Food Scanner app by ShopWell is pretty helpful, if you don't mind being that person mysteriously holding your phone up to boxes of food at the grocery store. (Join me at Trader Joes on 14th Street and we can do this together). But if you are monitoring a variety of ingredients, comparing nutrition labels can be overwhelming. Once you fill out a quick survey on this app, it stores all your nutritional preferences, such as fats, sugars and vitamins. It keeps track of allergies and tailors diets for those with diabetes or other health conditions. Scan a barcode and the app will tell you if the product meets your needs. If not, it will suggest something else similar. Helpful, but I'm a little disappointed that Marshmallow Hot Chocolate Pop-Tarts aren't recommended. The free app is compatible with iPhone, iPod touch, and iPad, but requires iOS 4.3 or later.
