Three minutes a day. No ads, no noise, no streak screaming at you.
Gyrus measures seven pillars of your cognition — memory, attention, speed, flexibility, logic, restraint, endurance — then builds a daily three-exercise session at your exact level.
MEASURED, NEVER GUESSED
A short assessment sets your baseline. Every session after it moves that number or leaves it alone — it is never nudged for encouragement. An untested pillar reads "not measured", never zero.
Two clean rounds: difficulty goes up. One error: it comes down. The same staircase psychologists use to find a threshold. Your index only moves when you do the session.
EIGHTEEN GAMES, SEVEN PILLARS
Memory — grids, secret codes, digit spans, shopping lists, pairs
Focus — spot the twins, the missing number, counting the flock
Speed — sorting under flow, judging quantities at a glance
Logic — flash arithmetic, treasure hunts, anagrams
Flexibility — switching between two rules without stalling
Restraint — linking dots without touching the traps, arrows that lie
Endurance — read across a whole session, not from any single game
Each pillar keeps its colour everywhere: in the catalogue, on the board, in the session report.
A FINISH LINE, NOT A CLOCK
Each game ends on a target rather than on time running out. Finishing early is worth something — the time you have left is a bonus you win, not a wait you sit through.
FOUR RELAXATION PUZZLES
Candy sort, Flow Link, the Tower of Hanoi and Take Flight. No timer, no pillar, no effect on your index. They occupy the mind, they do not measure it.
EVERYTHING STAYS ON YOUR DEVICE
Gyrus holds no account. Scores, history, levels and preferences live in your device's storage and nowhere else. Uninstalling erases all of it.
