There seem to be a couple of these devices in the works for release in 2017. I haven't seen much about them in the D community. here is one: https://www.consumerphysics.com/myscio/order/ It is the cheaper of the two I've seen. Basically, it is a handheld device which can scan your food and tell you (among other things) the carb count. It seems like this could be big for us, right? Accurate carb counts can make a huge difference.
