Stop guessing when.
Live by your real body clock.
Body Clock GPS is your personal timing intelligence layer. It turns continuous wearable signals into a daily rhythm map — peak focus, recovery dips, training windows, wind-down and sleep — so every decision lands at the right moment.
Tell you the what.
- — Steps, calories, sleep score
- — A wall of dashboards
- — Generic "8 hours, 10k steps" advice
- — You're left to figure out the rest
Tells you the when.
- When to do deep work
- When to train, when to rest
- When to eat, dim lights, sleep
- Specific to your body, today
One day. Six windows. Zero guesswork.
A sample rhythm map for a typical urban Indian chronotype. Yours adapts daily, based on last night's sleep, today's stress, and where your clock actually is.
10 minutes of outdoor light to lock your master clock and set the tone for tonight's sleep.
Cortisol high, reaction time sharp. Schedule deep work, strategy, and high-stakes calls here.
Natural alertness trough. Walk, hydrate, or take a 20-min nap instead of forcing through.
Body temperature, strength and VO₂ peak. The best window for training and intense workouts.
Melatonin onset begins. Dim lights, off-screens, lighter dinner — protect your sleep runway.
Deep sleep and REM cycles. Sigma confirms recovery quality and adjusts tomorrow's plan.
Sense. Model. Guide.
A closed loop between your ring, your context, and the day ahead — running quietly in the background so you don't have to read another chart.
The ring reads HRV, body temperature, motion and sleep architecture continuously, 24/7.
Sigma's AI fuses signals with your chronotype, light exposure and routine into a personal clock.
You get specific, time-stamped nudges — when to focus, eat, train, wind down and sleep.
Built for Indian lives, not Silicon Valley schedules.
Late dinners, monsoon light, festival nights, 9pm meetings, 5am workouts — Sigma's clock learns your real life and aligns gently with Ayurvedic dinacharya principles, without the dogma.
- Trained on multi-night HRV + activity data, not single-point spot reads
- Confidence-aware: shows you when the model is certain vs. still learning
- Adapts to travel, shift work, late nights, and Indian routines
- Aligns with Ayurvedic dinacharya — without the dogma
Hit two deep-work blocks a day without burning out by 4pm.
Train when your body is actually ready. Recover when it isn't.
Recover from late nights and time zones in days, not weeks.
Be among the first to live by your real clock.
