Explore free — AI timer, 19 ambient sounds, sleep & health insights. Unlock pro features for peak performance.
You track your workouts. Your sleep. Your macros. But not your focus.
Cortex is the AI brain performance toolkit for people who think for a living. Adaptive timer. Neuroscience sounds. Data that doesn't lie.
Not another meditation app. Not a basic countdown. A system that learns how your brain works and makes it work better.
AI ADAPTIVE TIMER
Cortex's AI mode analyzes your focus patterns and adjusts session length, break timing, and sound intensity in real-time. The more you use it, the smarter it gets. A smarter approach to focus timing.
STRUCTURED FOCUS MODES
Pomodoro (25/5) — Classic deep work intervals
Flow Mode (50/10) — Extended focus for complex tasks
AI Adaptive — Algorithm-optimized sessions
Custom Timers — Build your perfect work rhythm (up to 10 presets)
NEUROSCIENCE-BACKED SOUNDS
Brown noise, rain, ocean waves, binaural beats, lo-fi, tibetan bowls — selected for their proven effect on concentration and cognitive performance. Play during focus or sleep sessions.
SLEEP TIMER
6 sleep presets with gradual audio fade-out. Switch from peak performance to deep recovery in one app. Because sleep isn't rest — it's your brain's firmware update.
DATA, NOT FEELINGS
Focus Score — weekly performance metric
Peak Hours — know when your brain fires best
Heatmaps — visualize focus patterns over time
AI Weekly Reports — actionable recommendations based on your data
Streaks & Achievements — gamified progress that compounds daily
10 languages · Neo-brutalist design · No ads · No data selling
Built for people who use Notion, Linear, and Arc — not pastel wellness apps
Your brain is a machine. We help you run it at peak RPM.
