Three minutes of pure training

No ads. No noise. No streaks screaming at you. Just measurable focus.

Gyrus measures seven pillars of cognition and builds a daily program from what it actually observes. Nothing is estimated: a pillar it has not measured is shown as unmeasured, never as a zero.

The seven pillars

Each pillar keeps its colour everywhere: in the catalogue, on the grid, in the session report. One colour per pillar, never one per game — seven you learn, eighteen would mean nothing.

• MEMORYKeep more in mind at once
• FOCUSHold attention without drifting
• SPEEDDecide faster under pressure
• FLEXIBILITYSwitch rules without stalling
• LOGICDeduce what you are not told
• RESTRAINTWithhold the answer that comes first
• ENDURANCEHold the level to the last round

Measured, never guessed

A short assessment sets your baseline, and every session after it moves that number or leaves it alone. Difficulty follows what you actually do, one step at a time, never two.

Each game ends on a target rather than on a clock running out, so finishing early is worth something: the time you have left is a bonus you win, not a wait you sit through.

Everything stays on your device

Gyrus holds no account. Scores, history, levels and preferences live in your device's storage and nowhere else. Uninstalling the app erases all of it.

Two things leave the device, and only if you explicitly ask them to. The privacy policy names them exactly, field by field.

Coming to the App Store and Google Play

Gyrus is in development. This page exists so that the stores, and you, can read how the app handles data before it ships.
