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.

The home screen now refreshes itself when you return to the app, so your Thinking Score and energy timeline always show today — not yesterday. ### 2.3 — 2026-07-28 Your Thinking Score now tracks missed sleep the way your brain does: last night counts most, older nights fade over the week. One rough night no longer drags your score down for days. Your sleep need is now learned from your own best-rested nights — not a fixed 8 hours. Bedtime suggestions got realistic: they shift in small steps from your usual bedtime, so tonight's advice is one you can actually follow. ### 2.2 — 2026-07-25 New: the Grow tab. A short daily plan of practices — morning light, caffeine timing, evening wind-down — with each one's effect measured on your Thinking Score. Sharper within hours on the days you do them, building over weeks. Your daily score is now the Thinking Score — the same number, named for what it actually measures: how sharp you'll think today. We also smoothed out setup, so connecting Apple Health is faster and the opening screen no longer stalls. ### 2.1 — 2026-06-25 Your daily score is now the Thinking Score — the same number, named for what it actually measures: how sharp you'll think today.
