Knowt

Flashcards are one of the easiest ways to study before an exam, especially when you’re trying to memorize definitions or important facts.

Fortunately, you don’t need to spend hours writing everything on physical cards. Knowt is a study app that lets you create digital flashcards and review them directly on your Apple devices, and its core learn and spaced-repetition modes are free to use.

Knowt also includes different study modes, allowing you to practice the same material in several ways, which is perfect when you want to memorize many different topics. Another helpful feature is spaced repetition. This study method involves reviewing information at different intervals to help reinforce what you’ve learned over time.

And since it’s 2026, Knowt also offers AI-assisted tools that can turn supported study materials into flashcards and practice questions. This could save you time when preparing for an exam, although you should always check the information for mistakes.
