This would make my idea for a mobile app that renders pictures of the sugar/salt/fat content in foods by OCRing the label a trivial problem, and it could lead to many other applications like a shopping assistant for diabetics, athletes, etc.
This was the startup I was CTO at. We organized peoples' whole diets and we used the barcodes rather than OCR to get the nutrition facts of labeled products.
The product recommended home-cooked meals (web-only), found the healthiest restaurant dishes near you (mobile and web), and evaluated the nutritional fit of labeled food products in stores (mobile-only). The recommendation algorithm was all backend.
Too bad we got acqui-hired.
I didn't follow the acqui-hire and went on to work for a genetics startup.
Email me if you want more info or to see about making it exist again. We had an alpha test group of some very happy users :)
