Long-tap a word from your browser, email, news app, or social network to copy it. 4. Open this App from the background.

An effective method of memorization based on spaced repetition theory When you memorize foreign words(eg. Spanish, French), you can memorize nearly a thousand words in about a month, if you do it 30 words a day, unless you forget what you memorized before. According to the forgetting curve theory, one's memory falls exponentially as time wear on. There are various factors, such as the meaning of what you try to memorize, individual ability, but most people have little memory after a week. What's important here is repetitive learning, but it would be inefficient to repeat every thing every day. This is because, according to the spaced learning theory, the more you repeat it, the more flat the exponential function you lose your memory. So even though there are individual differences, for many people, reviewing one day after, three days after, seven days after, 14 days after would work well. We remember things for a long time with less time investment to repeat it by gradually increasing the interval. It will be effective in doing so. Memorida is an optimized solution to this type of memorization. It asks rarely things you remember well, and it asks more frequently things you don't remember well, so you could be more effective to memorizing them.
