In an age where we can track the quality of our exercise, sleep and diet via our phones, it was only a matter of time before someone came up with a cup that tells you exactly what you're ingesting.

Intrigued by the potential of digital activity trackers, the tech whizzes over at Vessyl decided to create a cup that not only identifies each drink that passes through your lips, but also tracks in real time the calorie, sugar, protein and fat content of said drink.

The Vessyl will tell you the exact nutrient content of what you're drinking via an LED screen on its side. If you're drinking out of a different cup (say, having a glass of wine) you can manually update data on your beverage of choice to the cup's app, which works in parallel with the screen info.

The app will then aggregate all the data it has on your drinking habits to let you know if you're hydrated enough, how many liquid calories you're drinking and if you need more protein.

The technology behind the cup is advanced enough to recognise major brands of drink, as well as yogurt drinks, smoothies and milk shakes. It can also keep track of how much caffeine you've had, with the potential to aid sleep and weight loss among other things.

Vessyl's team led by co-f0under Justin Lee, says: "We don't get into the specifics of how the technology works [but] we can tell you that there are sensors built in throughout the entire Vessyl. These are in the same realm of technology as quality control in the food industry."

The cups are being rolled out next spring for £60 a go and ten thousand people have already flocked to put in their pre-order since the Vessyl went on sale in June.

Whether we really need such a specific rundown of what we drink is debatable, but there's no denying the opportunities this impressive gadget carries for the future of diet tracking technology.
