Focus turns classic cognitive psychology and neuroscience paradigms into 3–15 minute drills you can actually finish every day. Sound familiar? · Your eyes are on the screen, but your mind already left · You know you shouldn't tap, but your hand still does · Afternoon fog makes two lines of text impossible · You want better focus—but don't know what to practice or whether it's working Focus does not diagnose or treat medical conditions. It is a repeatable brain fitness plan—train your attention networks like you train your body. 【15 SCIENCE-BASED DRILLS】 Four skill pillars, one tap to start: · Sustained attention — Focus Lock, Schulte Grid, D2 Attention, Vigilance Control · Impulse inhibition — Go/No-Go, Stroop, Flanker, Dimensional Shifting · Working memory — Dual N-Back, Spatial Span, Spatial Reverse, Visual Paired Associates, Rhythm Sync, Time Perception · Neural recovery — Coherent breathing and downshift exercises 【PROGRESS YOU CAN SEE】 · Daily goals and streaks for consistent habit building · 30 cognitive achievement medals · Analytics: accuracy, reaction time, and trend curves · Time-of-day coaching: morning, midday, dusk, and night 【BRAIN SCIENCE LIBRARY】 Every drill links to plain-language neuroscience—prefrontal control, dopamine networks, synaptic plasticity, and ADHD-related cognitive patterns. 【BUILT FOR DEEP WORK】 · Soft, eye-friendly palette · Optional pink / white noise and ambient sounds · Haptics and daily reminders (optional) · Chinese and English UI 【PRIVACY FIRST】 · All training data stays on your device · No account required · JSON export / import backup · No ad tracking of personal identity 【IMPORTANT】 Focus is a self-training cognitive tool, not a medical device. For ADHD, anxiety, sleep disorders, or other health concerns, consult a licensed professional. Start with 10 minutes a day.
