Smartphone app uses selfies to check your cholesterol level

A team of engineers has designed a smartphone accessory and app that allows users to monitor their own blood cholesterol levels. Think of it as a sort of cholesterol selfi, or maybe a healthie?

New tech being developed at Cornell University aims to bring cholesterol testing to smartphonesto make the numbers both more specific and easier to track. Home cholesterol test kits have been around since the early 1990s, catering to those with high cholesterol levels — which puts them at a higher risk of developing heart disease — who need to check their numbers more than once every few years.
