App To Buy. Now, Not Later.

Food Switch

A very food-savvy friend alterted me to this one to me and, in a word, it's genius. It's called Food Switch and it works like so: You're standing in the cold food section, debating the difficult issue of which vanilla custard to buy. You turn on Food Switch. You scan the barcode. It recommends healthier options. Simple as that. And you're out of there before your eyebrows freeze over.
