THE CURVE is a flashcards maker app that is not only based on an efficient & effective iterative learning method, but also adheres to the principles of the forgetting curve for optimal learning efficiency! You can learn various things anytime, anywhere. This app supports language learning, exam preparation, regular tests, qualification acquisition, and more! You can add as many words as you want to memorize, so let’s create your own original flashcards. With the learning mode, which is based on the correct answer rate, you can intensively review only those flashcards that you find challenging, ensuring that your study sessions align with the forgetting curve for maximum retention. Features: • You can create flashcards freely. • You can create multiple flashcards for various memorization tasks, studies, and learning objectives. • You can enter notes on both the front and back of the flashcard, which is convenient for including example sentences. • You can easily learn by simply tapping “Correct” or “Incorrect”. • By using the learning mode, you can review in an efficient and effective manner. • The app adheres to the principles of the forgetting curve, optimizing your learning efficiency. Learning Modes: You can choose from various learning modes based on your needs. These modes allow you to focus on specific aspects of your vocabulary. Here are the available options. Feel free to choose the mode that suits your learning style and goals! • Forgetting Curve Mode: Learn words based on the forgetting curve, which optimizes retention by reviewing at the right intervals. • All Flashcards Mode: Study all the cards in your set. • Unlearned Mode: Concentrate on cards you haven’t encountered yet. • Incorrect Answers Mode: Review only the cards you’ve answered incorrectly. • Correct Answers Mode: Reinforce your memory by revisiting cards you’ve answered correctly. • Challenging (Rate 40% or Less) Mode: Target cards with a low accuracy rate. • Challenging (Rate Under 50%) Mode: Focus on cards with moderate difficulty. • Challenging (Rate Under 70%) Mode: Tackle cards that need improvement. Learning and Review Based on the Forgetting Curve: • Leveraging the theory of “Ebbinghaus’ forgetting curve”, this approach prioritizes efficient learning through strategic review. • By repeating reviews at appropriate intervals aligned with the forgetting curve, you can enhance memory retention. • These review results are reflected in your “learning level”, indicating your degree of mastery. • Remember that consistent review, especially when memories are on the verge of fading, contributes significantly to long-term retention. Learning Levels Based on the Forgetting Curve: According to the forgetting curve, if you answer correctly after a certain number of days from your last learning session, your learning level will increase. Learning levels are represented by chess pieces, starting from Level 1 (Pawn). Here’s the breakdown. • Level 1 - Answer correctly after 10 minutes -> Level 2 (Knight) • Level 2 - Answer correctly after 1 day -> Level 3 (Bishop) • Level 3 - Answer correctly after 2 days -> Level 4 (Rook) • Level 4 - Answer correctly after 1 week -> Level 5 (Queen) • Level 5 - Answer correctly after 3 weeks -> Level 6 (King) • Level 6 - Answer correctly after 9 weeks -> Level 7 (Mastery Achieved) * Remember that if you make a mistake at any point, your level will reset to 0. Each flashcard has the following options: • Learn with shuffled flashcards. • Display the flip side of flashcards first. Night Mode: • Night mode is a switch to a darker theme than usual. • By setting a dark theme, you can use it without straining your eyes even when studying late at night or in bed. • Also, you no longer have to worry about disturbing others with a screen that is too bright.
