TellSpec is one of the most novel and talked about approaches to food tracking in recent months. It raised nearly four times it's $100,000 goal on Indiegogo. The device is a three-part system which includes a scanner, cloud-based algorithm and companion app. The scanner utilizes a spectrometer to send information to the cloud. More specifically, the spectrometer sorts the photons in the food by wavelength and then counts them. The resulting information, which is sent to the cloud, is also sent to the companion app, which can apparently work out information about allergens, chemicals, nutrients, calories, and ingredients.
The rocky road of professed nutrition tracking bracelet Airo shows just how invested -- and how skeptical -- people are in the search for accurate passive nutrition tracking. Allegedly, Airo’s nutrition tracker uses wavelengths of light to look into the bloodstream to detect metabolites, which are released during and after the user’s meal. These metabolites will tell the tracker how many calories were consumed during the meal. However, after the tracker was met with widespread skepticism, the company halted pre-orders and refunded early backers.
Eat It Tweet It is an iOS app created to integrate with Twitter and offer users a portal to tweet exclusively about their diet. The app, created at New Mexico State University, includes preset hashtags categorized as behavior or food and a camera feature to take a picture of the meal. A study conducted on the app showed that young adults found it useful for tracking food consumption, though it didn't look at weight loss outcomes.
