The energy curve

Steady knows which version of your day you're in.

From last night's sleep, Steady predicts your energy hour by hour and names the window you're in — so you spend focus where it lands, not where the calendar says.

Peak

Your sharpest window. Protect it for deep work and hard decisions.

09:00 – 13:00

Steady

Reliable, even energy. Good for meetings, admin, and momentum.

13:00 – 14:30

Dip

Natural energy drop — take a walk or handle light tasks.

14:30 – 16:00

Recovery

Wind down. Steady sets a bedtime that clears tomorrow's debt.

21:00 – sleep

Built around your baseline

Health guidance that stops pretending everyone has the same body.

Three engines run against your personal normal — and explain themselves in plain language, the moment you wake.

Circadian Coach

A schedule shaped around your body.

Deep-work, first meal, exercise window, and wind-down — each timed from your own rhythm, with a "Next" marker so you always know what's coming.

Health Radar

A morning confidence score from your own baseline.

Resting HR, HRV, sleep, respiration, temperature and blood oxygen, each compared to what's normal for you — flagged the moment one drifts.

Recovery & Strain

Rest is treated as signal, not failure.

Daily strain, waking pulse, sleep stages and habit patterns reveal whether today is for pushing, holding, or bouncing back.

One glance, full understanding

A calm health radar for mornings that matter.

Steady compares today to your own recent normal using personalised deviation scoring. The result is a plain-English confidence signal — with the details one tap away when you want them.

On your wrist

Steady lives on your wrist, too.

The native watchOS app mirrors your scores, energy state and next window so they're a glance away — plus watch-only tools built for moments your phone isn't in your hand.

Science without the panic

Personalised z-scores, weighted signals, responsible framing.

Steady is designed for wellness awareness, not diagnosis. It looks for multi-signal patterns and explains them as body context: when to recover, when to watch, and when your signals are returning to normal.

“The app reshapes itself around what's already happening — you never reorganise your day to fit it.”

Steady design principle № 1

Private by design

No accounts. No servers. Your health data stays yours.

Processing happens on your iPhone and Apple Watch. Steady uses your HealthKit context to benefit you — not to build a profile somewhere else. Zero analytics. Zero exceptions.
