About this game

LogicGrid is an offline brain trainer and focus toolkit. Play a pattern memory grid, test your reflexes, practice Stroop attention, and run a local countdown timer. No account. No internet. No ads.

FEATURES
1. Logic Grid pattern memory
Memorize highlighted squares on a 3x3 to 5x5 grid. The pattern flashes for two seconds. Tap the same squares. Correct patterns raise your score and level. A wrong tap ends the current run. High score is stored only on this device.

2. Reflex Tester
The screen stays red, then turns green at a random moment. Tap as soon as it turns green to see your reaction time in milliseconds.

3. Stroop Effect Test
Read a color word printed in a different ink color. Choose the ink color, not the word, to train focus.

4. Digital Detox Timer
A simple offline countdown in the Pomodoro style. Pick a duration and keep your attention on one task.

OFFLINE AND PRIVATE
This app works fully offline. It does not use the internet, does not create accounts, and does not collect personal data. Scores and timer settings stay in local app storage on your phone.

DISCLAIMER
LogicGrid is a casual training and focus utility. It is not a medical, clinical, or diagnostic tool.
