Cognitive Readiness · Apple Watch Required
Your brain has
peak hours.
Mozok uses the SAFTE biomathematical model — validated in sleep research and military aviation — to predict your cognitive effectiveness hour-by-hour from last night's Apple Watch data. Every calculation visible.

The Gap
You schedule by availability.
Not by biology.
Calendar apps know when you're free. They don't know when your brain is sharp. Oura gives you a morning recovery score and stops there. Mozok gives you a full-day cognitive map — with work-type recommendations for every window.
The status quo
Recovery scores stop at wake-up
Oura, Whoop, Garmin: one number at 7am, calibrated to population averages, never updated. No guidance on what type of work to do or when.
The status quo
Calendar apps ignore your body
Meetings scheduled around availability, not cognitive capacity. Deep work dropped into circadian troughs. The 2pm negotiation on four hours of sleep.
Mozok
Hour-by-hour cognitive effectiveness
A full-day timeline — peak windows highlighted, work type recommended, every input from your Apple Watch visible in the formula view.
Mozok
Your baselines, not population averages
14-day rolling median + MAD per metric. The model calibrates to you — not to a research sample of strangers.
The Process
Three inputs.
One honest curve.
01
Apple Watch collects the signal
Sleep duration, timing, REM and deep stages, HRV, resting heart rate, respiratory rate. No manual entry. No cloud upload. All data stays on your device.
02
SAFTE model generates the curve
Process S (sleep debt), Process C (circadian rhythm), and Process I (sleep inertia) combine into a Cognitive Effectiveness Score, updated on each app open.
03
Your schedule, aligned to biology
Peak windows are labelled: Deep Work, Meetings, Admin. You see the exact input values that drove each recommendation. Move a meeting. Protect a window.
Capabilities
Everything a scientific
instrument should do.
Morning Readiness Score
Composite score from sleep, HRV, resting heart rate, and sleep debt. Computed fresh every morning from your personal 14-day baseline.
Updated dailyHourly Energy Timeline
Cognitive effectiveness predictions from wake time to 10pm. Peak windows highlighted. Work type labelled. Trough zones flagged.
Hour-by-hourFull Formula Transparency
Every intermediate value visible: raw inputs, personal baselines, z-scores, weighted contributions. No black box. Audit every number.
Every calculation shownLocal-First, No Account
All data stays on device. JSON persistence. CSV export. No server, no sync, no account required. Your Apple Health data never leaves your phone.
Privacy by designUnder the Hood
The math is the product.
Mozok implements the SAFTE model(Sleep, Activity, Fatigue, Task Effectiveness) — a validated biomathematical framework from sleep research and military aviation. Predictive validity r = 0.4–0.7 in controlled studies.
