Cards for memorizing words, phrases, rules... You can learn a large amount of new foreign words, prepare for the exams and much more. The application uses spaced repetitions (spaced repetitions). The clue point is that the information must be repeated at certain increasing intervals. Spaced repetition technique allows all knowledge to be stored in long-term memory, I mean, years from now, you’ll remember the information. At the same time spending less time on memorizing. You just need to create cards with words/phrases/sentences. The cards themselves will be shown with an increasing time interval according to the interval repetition algorithm. The app will let you know when the next study will start.

About

Dopus

Read full description

For the Psychometric and the English Bagrut. 300 academic words, six weeks, five minutes a day. The vocabulary that wouldn't stick from a word list — finally sticks. You know the cycle. You open the list. You get through forty words. A week later "perfunctory" is gone again. Lists don't fail because you weren't trying — they fail because the word never had anywhere to live. Dopus drops every word inside a small, specific scene. A returned essay with one word circled in red. An apology that lands wrong. A street sign you don't quite read. You guess the meaning from the scene, and that guess is the thing your brain holds onto. THREE PHASES, BUILT FOR REAL MEMORY • Recognize — the word arrives inside a moment your brain can picture, with the definition close enough to reach for. • Understand — the training wheels come off. You apply the word in context, without the clue. • Mastery — the word returns just before you'd forget it, in a new scene every time, until it's locked in for good. Behind every question is FSRS, the most accurate spaced-repetition algorithm available — running quietly so you don't have to think about when to review. WHAT'S INSIDE • Psychometric English — the academic vocabulary the test actually weighs against you. • Psychometric verbal Hebrew — the high-register Hebrew words from the מילים and analogies sections. • Bagrut English, Yehida 5 — the full vocabulary expected at the highest level. • SAT, IELTS, GRE, TOEFL — for anyone preparing in English outside Israel. • Mnemonic questions with custom images and audio — for the words your memory refuses to hold. • News-based questions, generated daily — vocabulary in real sentences from the world this week. • Build a personal collection from any list, page, or textbook you paste in. PROOF, NOT PROMISES • 94% recall after 30 days — vs. ~28% for flashcard apps and ~41% for classroom drill. • 100 words in your first three weeks, at five minutes a day. • SAT students report an average lift of +90 on the reading section.
