Numbers are easy.
Knowing what to dowith them isn't.
Every tracker floods you with data. Helix turns yours into a single, clear move — every morning.
Recovery
Some mornings
you're ready.Some you're not.
Helix knows which — the moment you wake, from the inside out.
Measured against your own 60-day baseline — never a population average.
Cardiovascular strain
Strain thattells the truth.
Strain is a percentage of what your body can handle today, built from heart rate alone. A slow, heavy lift barely moves it. And a rest day finally reads like a rest day — not a number you earned by existing.
Your strain vs today’s recovery-adjusted ceiling.
Sleep
Sleep is where you actually recover.
Helix reads the depth and quality of every night — your stages, your regularity, and the ideal window to fall asleep — then turns it into tomorrow’s readiness.
Wear your Apple Watch for full stage detection. No watch tonight? Helix still captures your sleep duration from your phone and folds it into recovery.
Per-muscle recovery
Not one recovery score.
Sixteen.
Everyone tracks cardio. Almost no one tracks how your muscles recover. Helix models fatigue for every muscle group — so your chest can be fried while your legs are fresh.
VO₂max Lab
Watch your engine grow.
Trend +3.2 / year — every reading, one forecast.
Energy schedule
Your energy has a shape.
Helix maps when you’ll peak, when you’ll dip, and — as melatonin rises in the evening — when to start winding down.
You bring the work.Helix brings the truth.
Health Intelligence
An intelligencethat knowsyour body.
Ask anything. It answers with your actual numbers — last night’s sleep, this morning’s recovery, what you trained yesterday — not generic advice off the internet.

No band. No charger.
It's already on your wrist.
Helix runs on the Apple Watch and iPhone you already own. Nothing to buy. Nothing new to wear.
