Visual calorie-counting apps have appeared on smartphones before, but typically involved object identification through the camera (or barcode scanning, which isn’t quite the same). Other apps, with more expensive subscription costs, would direct your photos to people hired to work out what you were putting in your mouth.While this route would probably offer the most precise answers, it’s also not an instant one, and learning that delicious meat pie you ate for dinner goes over your calorie count for the day is no use once it’s already long gone. The NutriRay3D adds some hardware to your existing smartphone, scanning the contents of your plate with lasers for high-precision calorie and nutrient estimates — it’s looking to crowdfunding to make it all happen.
