The problem

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.

Our approach

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.

AI that decides with you
Personal models translate raw signals into clear, timed actions for your day.
Privacy-first
Your data stays yours. On-device processing where possible, encrypted in transit.
Affordable on purpose
₹4,999 ring + ₹199/mo app. A premium health system that doesn't gate-keep wellbeing.
