New: the Grow tab. Small daily practices, each measured against your own Thinking Score. Get sharper every week.
Your calendar doesn't know your brain. Mozok does.
Your Thinking Score updates every hour — a personal read on how sharp you actually are right now, built from last night's sleep, your body's daily rhythm, and how much rest you've been carrying.
Built for people who think for a living: founders, engineers, writers, researchers. The kind of work where three sharp hours outperform a whole unfocused day.
WHAT MOZOK TELLS YOU
• When you're sharpest — and for how long
• Which hours are built for deep work, which for meetings, which to protect
• How last night's sleep is affecting your thinking right now
• When to push and when your brain needs to recover
WHAT MOZOK HELPS YOU CHANGE
Your sharpness isn't fixed. The Grow tab gives you a short daily plan — morning light, caffeine timing, evening wind-down — and measures what each practice actually does to your Thinking Score. Some sharpen you within hours. Some compound over weeks.
THE SCIENCE (IN PLAIN ENGLISH)
Mozok uses the same alertness model used to assess pilots and air traffic controllers. It combines three signals your body actually generates: how much sleep you've missed, where you are in your daily rhythm, and how long you've been awake. Your Apple Watch feeds it automatically. No manual entry.
PRIVATE BY DESIGN
All data stays on your device. No account required. No server. Your Apple Health data never leaves your iPhone.
WHO IT'S FOR
Not for athletes chasing VO2 max. For the person who goes to bed at 2am still thinking about a problem, and wakes up at 6am still thinking about it.
Apple Watch is recommended. HealthKit access is required.
