The TellSpec handheld device beams a low-powered laser at the food you wish to analyze, measures the reflected light with a spectrometer, and sends the data via your smart phone, computer, or tablet to TellSpec’s servers in the cloud.
Those servers use this data to deduce information about your food that is of interest to you. This information is then displayed on your computer, tablet or smart phone so you can intelligently decide if you want to buy or eat the food.
TellSpec is currently under development, after raising three times its funding goal on Indiegogo. Shipping is slated to begin in August 2014. Its US$320 price tag includes one year of free analysis of food scans, with further analyses being made available through subscription plans.
