The app is a vocabulary learning system based on latest memory research combined with artificial intelligence and machine learning. It means that you will spend most of your time learning words that you don't know, not repeating those that you have learnt already. The app is adjusting to your needs as you study.

Featuring:
- 70,000+ words Dictionary so you can add a word to study directly from a dictionary
- 3,500 GRE/GMAT words separated for your convenience so you can study only those that you don't know

Learning language is difficult because a typical word has 4-7 meanings. A typical meaning in turn could be described by 3-7 synonyms. This can't be described by a single "one word - to - one meaning" flashcard.

It's when you want to be the best of the best, it is. When I tasked myself with studying 5000 words for GMAT/GRE that's when it all became apparent. That's when I realized that I have to learn multiple synonyms of the same sense. But I had flashcards of a sense all over the place. It's better if you learn all synonyms at once. But when you learn a word many times you don't realize that you also learning a synonym for the word, just because you don't know either of the words yet.

I spent multiple years and then I gave up. Because I didn't have time to write the app. Congratulations! Now YOU HAVE the app. I finally created it. For myself, of course, but I wanted to share it with you all. Enjoy!

The best known technique for remembering the words, the spaced repetition algorithm, is based on 30 years of research of Poland Dr. Wozniak and Co. (and is widely used in his SuperMemo app) However, I dramatically modified the idea so these two can't be directly compared. Original version tries to estimate intrinsic difficulty of the word and based on that difficulty (how many times you can't remember the word when you should!) creates repetition schedule, which in turn tries to estimate the intrinsic difficulty. It's all good, but in case of the words (his system let's you repeat "anything") I would argue that if you can't recall the word at the time you supposedly should - it means that the difficulty was too high and simply needs (and can!) to be decreased. (as opposed to overload you with rote repetition of something you don't understand, that is way too often)

The dynamic difficulty decrease in the app is achieved by learning sense of the word from a different angle:
1) more and more examples are given
2) visual queues will start to appear
3) It's almost like solving a puzzle (which also called an active learning) you will be given NEW context to recall the word. So you are learning to synthesize the language, TO USE the word!

Eventually you are learning to use the word. Linguists say that at that moment you have learnt the word for good: so you don't have to repeat it anymore. At this moment you have instant recall. It can't be any easier to recall it after that. It can't be any better than that.
