Acerca de esta aplicación
A calm daily workout for your mind. QZBrain is minimalist brain training —
memory games, attention drills, and mental math that adapt to you.
No streak guilt, no noise, no account. Just a quiet, focused way to practice
the skills you use every day: remembering, noticing, and working with
numbers.
THE 5-MINUTE DAILY WORKOUT
One tap starts a curated session: 5 games, about 5 minutes, no repeats — and
it runs at the difficulty you choose. The daily workout is free, always.
9 ADAPTIVE BRAIN GAMES IN 3 AREAS
MEMORY
Matrix Recall, Pattern Focus, Path Memory, Number Flow, Emoji Match, and
Reverse Recall. Memory games are untimed "complete the set" boards — no
countdown, calm by design.
ATTENTION & SPEED
Matrix Scan — quick visual scanning to sharpen focus and attention.
NUMBERS
Rapid Math — mental math practice where +, −, × and ÷ unlock as you level
up. Set Shift — a rule-switching logic puzzle that keeps your thinking
flexible.
ADAPTIVE BY DESIGN
Cognitive training only works when it meets you at your level. Every game
adjusts its difficulty to your performance, step by step. Four tiers —
Novice to Expert — unlock through real play, so a session is always
challenging, never crushing.
ONE HONEST SCORE
NeuroIndex (100–999) blends speed, accuracy, consistency, and the level you
reach. It measures your own practice in these games — nothing more, and we
will never pretend otherwise.
INSIGHT, NOT NOISE
• 30-day average and weekly trend
• Per-game breakdown and personal bests
• Milestones earned through real performance
ARCADE MODE
Survival runs with best-run tracking, kept separate from your training
progress. A quick high-score chase when you want one.
PRIVATE AND OFFLINE
• Works fully offline — train anywhere
• No account needed; your data stays on your device
• Light, dark, or system appearance, plus 3 themes
• Available in 11 languages
FREE AND PLUS
Free: the daily workout (always), 4 practice games, 2 arcade games, and the
default theme. QZBrain Plus — monthly, yearly, or one-time lifetime —
unlocks the full game library, all arcade games, advanced insight analytics,
targeted coaching tips, and extra themes.
Five quiet minutes a day. That's the whole ask.
QZBrain is a general wellness product for everyday cognitive exercise and
entertainment. It is not a medical device and does not diagnose, treat,
cure, or prevent any condition. Scores reflect your practice in the app, not
clinical or psychometric measures.
