A fitness band that passively measures your calorie intake, with no action needed from you, would be the wearable Holy Grail. And like the Holy Grail, experts say the technology will probably remain a mere legend for the foreseeable future.
Two calorie-tracking wearables inspired hopes and made bank in crowdfunding campaigns recently. One, the Airo, wound up refunding people’s money after it determined its AIRO wristband lacks the accuracy to deliver consistent results. Healbe’s GoBe, on the other hand, started shipping to backers earlier in 2015, and Engadget’s review says its calorie-counting function provides drastically erroneous results.
That seems to corroborate what Medici Technologies CEO Ries Robinson told us about the GoBe’s passive calore-counting last year: “The physical reality is, this is just ridiculous. It doesn’t work at a medical level. It doesn’t work at a practical level.”
