Gabor Brain Game + app for iPhone and iPad

This is a sight & brain training game app that uses Gabor patch images.

What is Gabor patch?
A kind of striped pattern created by a mathematical process called Gabor transformation.
It was developed by Dr. Dennis Gabor, who won the Nobel Prize in Physics in 1971 for his invention of holography.
It was originally thought that viewing Gabor-transformed images is likely to affect the visual cortex of the brain.
Because of its action on the visual cortex of the brain, it is said to be effective not only for nearsightedness but also for presbyopia, astigmatism, and farsightedness.

How to play
When you press the start button, the Gabor patch image is displayed. Shortly thereafter, several other Gabor images appear on top of it and disappear. Remember where the Gabor patch image disappeared and tap it. If you tap all the parts of the Gabor image that disappeared, the next screen will appear. Each time you erase one, the score will be added. If you make a mistake, its over, but you can try again and again. There are currently 5 categories, so you can choose and challenge your favorite category every day. (Categories and images will be added regularly)

Goal Calendar
The number of correct answers is counted when the game is over. If its your highest score for the day, it will appear in your goals calendar.
If you set and clear a daily goal, the number displayed on the goal calendar will turn red. Make it a monthly goal to have all your favorite games displayed in red.
