Lumen is a crowdfunded tracking device which purports to analyze your breath to determine what state your metabolism is in. Now, the company behind it is launching an app for the Apple Watch to make it easier for you to use the hardware when you’re on the go. Users will be able to use the device and then see the results on their wrist, in a way that CTO and co-founder Avi Smila says “seamlessly integrated into daily life.”
The pitch for Lumen is, essentially, to enable you to learn as and when you should be eating and in what quantities. The system can tell you when you should eat, based on your metabolism, and suggests carb servings, meal plans and macros for the day. Should it be a lack of a smartwatch app has held you back from buying a Lumen thus far, you can pick up a unit for as little as $199, plus a monthly subscription of $19 a month.
