Health wearables tell you what happened. Almost none tell you what to do next.
Sleep that doesn't restore
Hours in bed don't equal recovery. Most people wake tired without knowing why.
Focus at the wrong time
We push hard when our body is winding down, then crash through the day's real peak.
Stress you can't see
Chronic load builds silently. By the time you feel it, it's already cost you weeks.
From passive tracking to intelligent guidance.
Sigma Life is a closed loop: a continuous-sensing ring, an AI app suite, and a Body Clock GPS that times your day to your physiology — not your calendar.
Navigate your day by your circadian rhythm.
Body Clock GPS predicts your daily peak, dip, and wind-down windows from continuous physiological signals. Eat, train, focus, and sleep at the right time — not the convenient one.
- Personal peak performance windows
- Smart wind-down + sleep onset prediction
- Adaptive recommendations as your day shifts
One ring. One app suite. A closed health loop.

"The Ayurvedic alignment view is what every wearable in India should ship with. It just makes sense."
