Human Performance OS · Hyderabad, India

The fashion brand that reads your body.

Apparel is dumb. Wearables are annoying. Nobody is watching the body doing the work.

Existing posture correctors rely on adhesives that fail in heat and humidity. Fitness bands are one more device to charge and forget. None of them connect what's happening physiologically with what's happening biomechanically.

Four touch points. One body intelligence model.

Each product stands on its own. Together, worn as your daily wardrobe, they build a picture of your body no single device can see.

01 / RING
Sthira Ring
Physiological intelligence
Grade 5 titanium biometric ring with dual-surface PPG — a design that's both more accurate and architecturally distinct from single-band competitors. Continuous HRV, heart rate, SpO2, skin temperature, and sleep staging, worn on any finger.
₹12,999 8-day battery · IP68
8 sizes, S/E Asian fit
BLE 5.3 · on-device AI
02 / CLIP
Sthira Clip
Biomechanical intelligence
A single magnetic clip, smaller than a shirt button, that auto-detects its own placement — collar, belt, or gait — and switches sensing mode with no manual input. Neck flexion, lumbar posture, pelvic tilt, sitting duration, stride quality.
₹8,999 10-day battery · IP55
22×14×7mm · 3 modes
Auto mode-detection
03 / WEAR
Sthira Wear
The ecosystem you already put on
Shirts, belts, and a corporate jacket engineered with built-in magnetic docking zones and conductive contact patches that improve Clip's sensing accuracy by ~40%. Fully machine-washable — Clip snaps out in under 3 seconds.

Posture-reinforcing seams
Anti-microbial, moisture-wicking
04 / SOLE
Sthira Sole
Gait & balance intelligence — new
A cut-to-fit insole with a 16-point plantar pressure array that closes the loop Clip's belt-based gait estimate can't fully reach: real stride data, weight distribution, standing time, and balance/fall-risk signals.

16-point pressure array
"Your Ring shows a stress spike. Your Clip shows your posture collapsing at the same moment. Your Sole shows your weight shifting off your left foot. This is your personal early-warning pattern — not three numbers, one signal."
