Cortex Brain Training. Pay once, no subscription, no tracking.
Seventeen focused brain games and classic puzzles in one calm, distraction-free app, plus Peak Hours: a personal cognitive
instrument you won't find in other brain trainers. Buy it once and own everything forever. No subscription, no ads, no accounts, and nothing leaves your device.
PEAK HOURS
A quick reaction check you can take any time of day. Over time it charts when your mind is sharpest and reveals whether you're a morning lark, a night owl, or steady all day. Fully private, stored only on your phone.
THE GAMES
Memory, focus, reading, timing and spatial skills, each built around a real task:
- N-Back, Sequence Memory and Remember-To for memory (including prospective memory, the skill of holding an intention)
- Stroop, Track and Peripheral Vision for attention (Track is the multiple-object-tracking task used in sports-vision training)
- Schulte Table and Speed Reader for visual scanning and reading
- Mental Rotation for spatial reasoning
- Inner Clock for your sense of time
- Number Sequences for pattern reasoning
SKILL DRILLS
Practical skills you can actually use:
- Mental Math: learn a real trick (multiply by 11, square numbers ending in 5, fast percentages), then drill it
- Speed Math and Estimation for arithmetic fluency and number sense
CLASSIC PUZZLES
- Nonogram: solve the number clues to reveal a hidden picture
- Sudoku and Word Search, as pure puzzles
PAY ONCE, YOURS FOREVER
A single one-time unlock opens everything. No weekly trials, no renewing subscription, no surprise charges. Sample several games free first, then unlock the rest for good.
PRIVATE BY DESIGN
There are no accounts, no analytics, no advertising, and no third-party trackers. The app works fully offline, and your stats
stay on your phone. Privacy here isn't a setting you switch on; it's how the app is built.
BUILT FOR FOCUS
A precision, dark-first design made for concentration, not a candy-coloured slot machine. Track your personal bests at your own
pace and watch yourself improve over time.
