What is Mozok?

Mozok processes data from compatible devices to create a personalized readiness curve that spans the waking hours. This curve highlights periods suited for demanding tasks alongside times better reserved for lighter activities or recovery. The tool breaks down how prior sleep quality and other physiological signals influence the current score. Users receive one focused recommendation each day aimed at raising future performance values, with follow-up tracking to assess results. All computations occur locally on the device without requiring accounts or external data transmission, allowing the model to refine its baseline over successive days based on individual patterns.

Delivers one specific, scoped daily nudge with projected score improvement
Personalized baseline that adapts to user's chronotype and historical data
On-device processing with no account, cloud sync, or telemetry
History view and built-in science library for inputs like HRV and circadian rhythm

What you can use Mozok for

Optimize Daily Focus Windows

Mozok maps hour-by-hour cognitive peaks and troughs from wearable data so users can schedule demanding mental tasks during their personal high-readiness periods.

Improve Recovery Through Targeted Nudges

The app analyzes sleep, HRV, and heart-rate inputs to deliver one specific daily recommendation that directly lifts the next day's Thinking Score.

Understand Personal Circadian Patterns

Mozok visualizes an individual's 24-hour readiness curve, including morning peak, afternoon dip, and evening fade, without relying on population averages.
