Your Living Sundial

The wearable circadian health tracker that reads your body's inner clock

SolaLoop continuously measures 12 biomarkers—cortisol, melatonin, glucose, HRV, plus light exposure—to tell you the optimal time for 25 daily activities. When your rhythms drift, personalized recommendations "boomerang" back to correct them, using data from thousands of users to refine predictions.

The Wow Moment

You wake up groggy, glance at your wrist, and see your personal sundial glowing amber—it's telling you your body thinks it's 3am even though it's 7am. The app explains: "Your cortisol spike is 4 hours late because of your screen time last night. Go outside now for 12 minutes of sunlight to reset." You do, and watch your sundial physically rotate toward your optimal time zone as your body syncs.
