Health Tracking

Stop Paying $30 a Month to Track Your Own Heartbeat. Try This Instead.

You bought the wearable, but you still pay a monthly fee just to see your own biometric data. It’s an absurdity that has become standard. But a new open-source project called noop 10.0 just shattered the illusion, proving you don’t need premium hardware or a subscription to track your fitness—you just need the software.

Your $1,000 CGM is Obsolete. Why Sweat is the Real Future of Health Tracking.

UCSD’s new sweat-tracking smart ring might not beat CGMs on accuracy yet, but dismissing it as an inferior substitute misses the point. The real breakthrough isn’t a single device, but the multi-modal sensor fusion combining sweat analysis with Raman and mid-infrared spectroscopy—the first real step toward needle-free, ambient health tracking.
