Benkyo Box is a flashcard app that is like your notes, but of the things that you want to commit to memory like names, fun facts, or exam material. These are the facts that you don't want to bury in a note taking app, and want to ensure you truly know them. Every flashcard you add to Benkyo Box is added to your daily studies, in which a beautiful study interface shows you the card’s question, you try to recall its answer, reveal it, then rate yourself after seeing the actual answer. Based on that rating, the card is re-surfaced in future with a notification so that you can practice again until you know it. Flexible flashcard content: Flashcards not only have the standard image/text front and back format, they also support in-app sketching and images for both the question and answer. Text supports multiple lines in both the question and answer so you can learn lists in a single flashcard. Powerful annotation cards: Looking to learn concept of an image? Like: - the components of a mechanical object - anatomical parts - different elements of a dish Benkyo Box makes this easy with Annotation Cards - simply annotate an image with arrows, rectangles and other tools, which automatically turn into flashcards. It preserves the original image as incredibly useful context. Easily create study material: - Natural Language: No need to enter questions and answers in flashcards! Enter a statement you'd like to learn, and with Apple Intelligence, we'll rewrite it as question and answer (Advanced Learner feature). - Quick Entry: Enter many cards at once by alternating questions and answers in plain text. This is specially helpful for pasting content from LLMs or adding multiple cards during a meeting. - CSV import: import a spreadsheet with flexible options on how to interpret the columns for the final flashcards - Folder import: select a folder with multiple images, creating a flashcard for each image in the question, filename on the answer. If the folder contains a CSV, the CSV can be used to customize how the images are imported (used as question, answer or both). Shortcuts for everything: Quickly do almost anything that you can do in the app within Shortcuts, like adding cards, checking your study status, importing content, and even updating app settings. Flexible organization: Organize your flashcards using folders and subfolders for all your topics, or keep them in the default unsorted folder if you prefer them that way. Your schedule and trends, at a glance: Open the app and you'll immediately see your study progress for the day and the time for your next study (also available as a widget). Navigate to the calendar to see what you have scheduled for today, the following days and how you scored the previous day. Flexible study sessions: Study a specific topic by navigating to it, or study all topics scheduled for today by studying from the Today view. Study times and flashcard frequencies can be configured in settings. Also if you are feeling like studying a topic but the cards are not available yet, you can always reset the folder and study right away. Privacy: Cards are private information and we have no access to them. If you use iCloud sync, Benkyo Box securely encrypts your content in iCloud with client-side encryption - nobody in the server can read your cards. Themes, each with a Dark Mode version: Choose a theme to match the mood of the study session. Advanced Learner Features: With Advanced Learner, a paid tier, you get features that help you streamline your studies: - Add cards using natural language - Extract cards from text and articles using on devices that support Apple Intelligence - Hidden folders that are ignored from studies until you are ready to unhide them - Deadlines that help prioritize studies before an important date Most importantly, the app is fully functional without Advanced Learner and we work hard to ensure that it’s easy to unsubscribe from it with the least disruption as possible.
