hmmm I suppose it would be cool if it actually existed, I would be VERY hesitant to fork over my money right now. Per the company website, they are "raising funds for the development and manufacture of TellSpec"... so, yeah, what looks like a "preorder" (which leads the person that orders to assume there will actually be a delivery of the product at some point in time), is actually a request for venture capital.
I would love to see these guys on Dragons Den/Shark Tank.
hmm there seems to be a lot of skeptism about this on the internet. I know nothing about the field myself. I think it would be worth it (if it works) if you suffer from food allergies but otherwise i would just rely on the free fooducate app. :)
