Welcome to Prohor's world of Mnemonics ! Are you a forgetful person? Whether it’s silly, like forgetting to do your homework, or something serious like missing a doctor’s appointment, a neglectful mindset can lead to serious damage. Well, no need to stress, this can be improved easily, while having fun. Mnemonic's intentions are to improve your hippocampus, the part of the brain storing information for memory. Therefore, forgetfulness hopefully won’t be a trouble for you anymore. Mnemonics is a timed object matching game, which challenges you with difficult patterns and colors as it goes. This is a simple game, but deceptively useful in practice. Playing this occasionally will sharpen your focus and attention. You will also be able to analyze more indirect information with an improved peripheral vision. Overall, you'll gain better memorization skills, and not just for those silly objects shown in the games. Harder levels come with brain-sweating materials. So start with the easy ones, and only when you are comfortable to move on put more stress on your brain with the harder levels. This app is developed by me, Prohor Nishat. I am only 10 years old and had to use my dad's account to publish Mnemonics for you. Hope you enjoy the playful and colorful world of Mnemonics.
