Most habit apps are just glorified checklists. Cortex is different — it combines daily tracking, streak analytics, and AI-powered coaching into a system that actually helps you understand why some habits stick and others don't. Track. Reflect. Improve. Log your habits in seconds, then let Cortex do the heavy lifting. The AI analyzes your patterns — which days you struggle, which habits are slipping, what's holding you back — and gives you personalized recommendations to get back on track. Key Features: Habit Tracking — Clean, frictionless daily logging with streaks and completion metrics Calendar View — See your consistency across weeks and months at a glance AI Coaching — Personalized insights based on your actual patterns, not generic advice Journal + Notes — Reflect on what drove good and bad days to strengthen your system Analytics Dashboard — Track success rates, streaks, and day-of-week performance Dark-mode first design — Minimal UI that stays out of your way Built for people who want more than motivation Motivation fades. Cortex helps you build habits that compound — by making it easy to track, easy to reflect, and easy to understand what's actually working. If you've tried habit apps before and fallen off, Cortex is worth another shot.
