What makes Calx different from a fitness tracker?
A tracker records what happened. Calx builds a digital twin — a model of how your body responds — that learns your baselines, discovers your patterns, and forecasts your next seven days. The coaching adapts to you instead of handing you a generic plan.
How does the voice coach work?
Tap the orb and speak. Calx transcribes your voice, reasons over your recent health data with a live agent, and replies out loud — the sphere shifts blue while listening, violet while thinking, green while speaking. It remembers the conversation for next time.
What are Aura and CalX Coins?
Aura is your identity score — recomputed nightly on the server from what you actually did, so it can't be bought, and it ranks you on the leaderboard. CalX Coins are reward points you earn from workouts, logged meals and hit goals — redeem them in the CalX Store for discounts on products and to win gift cards.
Which devices and apps does it connect to?
Calx syncs steps, sleep, HRV, resting heart rate and VO₂max from Apple Health and Google Fit, and reads any wearable those platforms support. The more it sees, the sharper your twin becomes.
Is my health data private?
Yes. Data is encrypted in transit and at rest, isolated per user with row-level security, and never sold. You can export everything or delete your account at any time.
What does Calx cost?
Calx is a subscription: Starter ₹499/mo, Pro ₹1,499/mo (30 voice minutes) and Elite ₹2,499/mo (90 voice minutes). One plan unlocks the coach, your adaptive plans and your digital twin. The muscle map is free to explore before you subscribe.
