Flashcards are a widely favored study technique, enabling learners to process vast amounts of information and filter out familiar concepts. However, manually creating and transporting hundreds of index cards for on-the-go review can be cumbersome. Thankfully, modern apps offer a more efficient, paper-free solution. Here are some top recommendations.
StudyBlue

StudyBlue enables users to collaborate by accessing flashcards created by others on related subjects. You can join or form groups to exchange relevant study materials with peers focusing on the same topics. The app supports adding images and audio to flashcards, self-assessment quizzes, and study reminders. It is available for free.
Accessible on Web, Android, and iOS.
Quizlet

Quizlet stands as one of the most extensive online platforms for flashcards. Its app seamlessly integrates with the website, allowing you to access and study flashcards from your mobile device. The interface is user-friendly with a clean, intuitive design. You can engage with your flashcards through interactive games, self-generated quizzes, or by simply browsing through your sets. Quizlet Learn develops a customized study schedule based on a deadline you provide. Similar to StudyBlue, you can enhance the app’s functionality by subscribing to Quizlet Go, which enables offline studying and eliminates ads. For additional features like personalized study options and progress tracking, Quizlet Plus is available at $47.99/year. Both premium plans include a 7-day free trial.
Accessible on Web, Android, and iOS.
StudyStack

StudyStack transforms your flashcard learning into an engaging game-like experience. The app offers various interactive activities such as crossword puzzles, hangman, matching games, hungry bug (a snake-inspired game), and word unscrambling. As you play, you earn pie chart segments that track your progress. Similar to other apps, you can explore existing flashcard sets, test yourself, and interact with the cards. However, StudyStack stands out by allowing more than two sides per flashcard. While the interface may lack refinement, its innovative features and free access make it a compelling choice.
Accessible on Web, Android, and iOS.
Brainscape

Brainscape is designed exclusively for flashcards, avoiding flashy features like quizzes or games. Instead, it emphasizes strategies to help you master the material on your flashcards as quickly as possible. The app asserts it can double your learning speed by customizing the timing of each flashcard based on your familiarity with the topic. It also partners with educators and publishers to develop flashcards for various subjects and provides additional insights on each topic. While some flashcard sets are free, many require a subscription. Pricing starts at $9.99/month, with options for $41.99 per semester, $59.99 annually, or $129.99 for a lifetime membership.
Accessible on Android and iOS.
Studies

Studies is an ideal app for individuals who prefer taking notes on their laptop and wish to effortlessly convert them into flashcards. A standout feature is its ability to organize flashcards into stacks (collections of flashcards) and groups (collections of stacks or groups). This flexibility allows you to tailor your study sessions by reviewing all flashcards, specific groups, or custom sets. The desktop app also lets you add tags to flashcards and provides detailed statistics on your study progress, including retention estimates. However, there’s no free version or trial; it requires a one-time payment of $4.99 ($24.99 for Mac compatibility).
Accessible on iOS and Mac.
AnkiApp

AnkiApp is a user-friendly flashcard application that tracks your performance after each study session. It uses this data to determine which flashcards to prioritize in future quizzes. You can either utilize pre-made flashcards or create your own, incorporating audio, text, and images. For enhanced features like advanced analytics and cross-device synchronization, AnkiApp Unlimited is available for $9.99/year or a one-time fee of $24.99.
Accessible on Windows, Android, Mac, and iOS.
