Memorize your passwords, important number information, historical event happening years using these images, symbols !! Num Num enables you to memorize easily with images, which is proved the easiest and ever lasting memory technique. Brains remember images incredibly in detail, which is the result of hard evolution of human or animal life. The memory techniques are also very old skills back to B.C. era. These memory skills are forgotten for decades, and more with the presence of smart phones. Ironically SMART PHONE makes people dumb. Num Num is created for those modern people who don't need remember many things, but want to be SMART !!! With these elaborately designed 30 icons, you can memorize 3 numbers with one image with 3 icons which makes one sentence.
