Create your own original question sets and efficiently study with a spaced repetition schedule tailored to the forgetting curve. ◆ Creating Question Sets ◆ ● In addition to questions and answers, you can also add explanations and pronunciation. In addition to the basic question-answer format of flashcards, you can also add explanations and pronunciations. You can toggle their visibility based on the situation. ● Images can also be added. By adding images, you can create questions that cannot be expressed in words alone. It's also useful for visual memorization. ● Supports adding multiple answers Unlike the typical flashcard one-question-one-answer format, you can add multiple answers to a single question. This is convenient when a single word has multiple meanings. ● Supports automatic voice reading If you want to have items read aloud automatically, you can select a language, and it will read aloud the questions during the presentation. This can be useful for listening practice and more. ◆ Enhancing Learning Efficiency ◆ ● Three learning modes There are three modes: Choice Mode, Typing Mode, and Test Mode. You can change them according to your learning progress and preferences. ● Learning management by mode Instead of having one schedule per item, learning progress is managed separately based on question orientation and presentation method. This ensures more effective memorization. ● Customizable question scope You can set the range and number of questions to be presented from your flashcards. You can also change the order and orientation of presentation. ● Automatic learning progress tracking Learning progress is automatically tracked just by solving problems. It can avoid presenting items that you already know to some extent. In review mode, you can also schedule reviews according to the forgetting curve for longer-term retention. ● Manual learning progress management You can manually mark cards you want to check individually. Of course, you can use this information to set the items to be presented during the quiz. ● Setting spaced repetition schedules according to the forgetting curve Shortly after learning, forgetting tends to happen relatively quickly. However, through review, you can correct the forgetting curve. After a certain period, the rate of forgetting slows down. It is said that reviewing around the time when you are about to forget is the most effective for memory consolidation. In this app, the review items in review mode are automatically scheduled for appropriate review dates and times. ● View your learning records You can view your weekly and monthly study time in graphs, as well as your total study time. ◆ Other Features ◆ ● Compatible with Mac, allowing editing and viewing on any device Since it is also compatible with Mac, you can use it on your favorite device according to your convenience. ● Changeable theme colors You can change the theme colors to your liking. ● Backup via iCloud and sync between devices You can back up your data with iCloud, so you don't have to worry about data loss. You can also share data between devices. ● Automatic backup feature You can automatically back up all your data every time you start the app. ● Lock the app with a password You can lock the app with a password to securely store your data. ● Data import and export feature You can freely import and export data. This allows you to exchange data with others or use your data in different apps. ● Import in CSV format It also supports importing in CSV format, so you can create question sets in your preferred app or import question sets you've created in the past.
