‘One day you stop learning and you start dying’, said Albert Einstein, probably the most famous physicist of the 20th century, who lived in a clear mind to a ripe old age. He also said, ‘My main wealth is my knowledge. Each knowledge forms a new neuron in the brain in which it is stored. Someone has millions of dollars in their account, and I have millions of neural connections - this is my wealth, which I earned by craving for knowledge.‘ The craving for knowledge at any age is the main rule for maintaining a clear head. I can confirm Einstein's words. I am almost 64 years old and I created this application alone, without helpers. Believe me, this is an exciting adventure. I also solved almost all the tasks and completed almost all the exercises that are presented in this application. I get a powerful emotional uplift from this. At 45, the human brain begins to age. There is nothing surprising in this, this is a normal physiological process, the same as, for example, a decrease in endurance and a decrease in muscle strength in elderly age. The first sign of brain aging is forgetfulness, which begins to torment even those who are still in their 30s. If no action is taken, the process of brain degradation accelerates and eventually into the terrible disease of dementia. If we stop walking, then soon our legs will atrophy as unnecessary. Similarly, the brain, if you do not give it work, begins to function more and more slowly, worse and worse. But brain aging can and should be stopped. When our muscles are decrepit, we go to the fitness center, where regular training helps to regain the tone of our body. The same training is required for our brain. All types of thought processes are called cognitive abilities of a person: perception, memory, problem solving, imagination, logic and the assimilation of new knowledge. They require constant training to maintain their level. This is especially true for older people. Prevention of cognitive impairment (dementia) is one of the main goals of modern medicine. Scientists have designed many exercises to prevent the deterioration of human mental faculties. Games exercises play an important role in this matter. Cognitive IQ is a collection of cognitive games to help you maintain and develop your cognitive abilities. Games on a red background train your reaction, games on a blue background help to improve attentiveness, and games on a green background develop memory. Games on a grey background develop logic and stimulate general cognitive activity. In the new version, this application is supplemented with daily exercises for the development of intelligence. When we work out in the fitness center, we use the services of a trainer. Similarly, for training the brain, a coach is needed who will help our mind to work constantly. In this application you will find such trainer - Cognitive Challenge. For a qualitative assessment of cognitive capabilities, this app uses the relative Cognitive IQ index. This index takes into account the dynamics of results when performing game training of the user's cognitive capabilities. Game results are reflected in the increase or decrease of this index.

Cognitive Challenge is a brain-training game built on the Stroop effect — the classic psychology test where the word and the ink colour disagree, and your brain has to fight the urge to read. In practice: the word BLUE printed in red. Tap the ink colour, not the word. It sounds easy. It isn't. That tiny pause is your brain overriding a habit — and training it is the whole game. FOUR WAYS TO PLAY • Classic — tap the ink colour • Reverse — ignore the ink and tap the word • Speed — the same challenge with less time • Tricky — word and colour randomly match or clash, so you never settle into a rhythm BUILT TO TRAIN • 8 colours and endless generated rounds, so there is nothing to memorise • Levels that unlock as your score climbs • Instant feedback with haptics, so mistakes actually land • Statistics that show how you really perform, not just your best score • Daily streaks to keep the habit going WHY IT WORKS The Stroop test has been used to measure attention and cognitive flexibility for nearly a century. Cognitive Challenge turns it into something you can practise in two minutes a day. Works offline. No account, no signup. Free to play, supported by ads.
