Your brain has
peak hours.
Mozok measures your cognitive readiness hour by hour — modeled from your wearable data and computed on-device. Two cognitive peaks. One mid-day dip. Every value visible.
Work when your best focus actually happens.
Mozok turns sleep, HRV, and circadian rhythm into a single, honest readout: when to think hard, when to coast, when to rest. Then it helps you reshape the day around it.
See your day before you live it.
An hour-by-hour readiness curve with your two cognitive peaks marked, your trough named, and your evening fade plotted from the moment you open the app.
Sleep and health, read for cognition.
Mozok pulls apart last night — total sleep, deep and REM minutes, HRV, resting heart rate — and shows exactly how each one moved today's score, up or down.
Coach the score upward — not just read it.
Specific, scoped nudges that move the math: a 23-minute earlier bedtime tonight, 20 mg less caffeine after 2 PM, a 12-minute walk to clear inertia before your peak.
One screen. Your whole day.
Today screen pulls last night's sleep, your live readiness, the curve ahead, and one actionable nudge — without a single notification, badge, or streak in sight.
- Cognitive readiness score — a single number on a full-arc readout, color-coded against your baseline (not anyone else's).
- Live curve — your day, hour by hour, with a “now” bead that walks across as you do.
- Best work, mapped to the hour — deep focus, creative, communication, admin: each suggested at the time your biology is built for it.
- Guidance to improve — specific, scoped changes (sleep, caffeine, light, movement) with the projected lift attached.
- History — every day's score and inputs, side by side, so you can see what's actually working.
- Learn tab — a built-in library of the science behind the score: chronotype, sleep pressure, HRV, recovery.
- Tap any number — to see exactly which input moved it, and how far.
Strong morning. Use it.
A baseline of one. Yours.
Population averages don't sleep your nights. Mozok learns your chronotype, your typical sleep pressure, your HRV ceiling — and recalibrates after every signal it sees.
Day one: already yours.
Mozok reads up to 90 days of historical sleep, HRV, and heart-rate data the moment you connect your wearable. Your personal baseline and recommendations are ready before you finish onboarding — no two-week wait.
Every night refines the model.
Each new night feeds back in. Your peaks shift earlier or later, your trough deepens or fades, your evening boundary moves — and the recommendations change with them, never a generic average.
You are a 24-hour wave. Mozok plots it.
Body temperature, cortisol, melatonin, alertness — every signal that runs your day rises and falls on a roughly 24-hour cycle. Two cognitive peaks, one mid-afternoon dip, an evening fade as melatonin starts to climb.
Mozok reads where your wave is right now — not the textbook version. Then it shows you the next 16 hours so you can put your real work into your real peaks.
Sleep banks energy. Your circadian wave decides where to spend it. Inertia steals the first hour after waking. Mozok keeps score, every minute of every day.
A score you can actually move.
Mozok doesn't stop at “84 / 100.” It tells you which input is the bottleneck, what one change would do, and watches the next night to see if it worked.
Bedtime 23 minutes earlier tonight would lift tomorrow's morning peak from 84 → 90. Caffeine after 2 PM is your largest drag this week.
You went down at 22:51. Sleep efficiency 91%. Morning peak 91 / 100 — projected was 90. Same thing tonight?
Trough begins in 32 minutes. A 12-minute walk + water recovers ~6 points and shortens it by half. Your last 4 attempts succeeded.
From signal to suggestion to evidence.
Most apps stop at the metric. Mozok closes the loop:
- Specific. “23 minutes earlier” — not “sleep more.”
- Scoped. One change at a time. The math says which.
- Measured. The next morning's number tells you whether it worked.
- Honest. If a habit isn't moving the score, Mozok says so and drops it.
A scientific instrument, not a wellness app.
Four readouts. No streaks, no badges, no notifications nagging you about steps.
Hour-by-hour readiness
A 16-hour forecast drawn from now to bedtime, updated every minute as new signals arrive.
Sharpest-window detection
Your two cognitive peaks, named. Mozok sizes them, scores them, tells you what to spend them on.
Trough warnings
A specific dip window with duration and a doable recovery action you can fit between meetings.
On-device. Always.
No cloud sync, no account, no telemetry. Sleep stages and HRV stay on the phone they came from.
