Kortz - Spaced Repetition Language Flashcards

Learning new language requires a proper mix of tools. Our flashcards app, with a gamified approach inspired by the Leitner System, is your ideal partner.

App Interface

Smart Memory Boost

Our app adds a playful touch to spaced repetition, drawing inspiration from the Leitner System.

Flexible Learning

Create custom flashcards that match what you're studying across various learning resources.

Steady Progress

Elevate your learning with our organized review system that helps you remember better.

Features

Our spaced repetition approach stands out due to its unique combination of properties. Learn more about it here

Operates offline, excluding features that inherently require an internet connection (such as: cards sharing, context learning)

Context learning with AI generated examples

Train subjects with their definite articles (if available in your target language)

Use across multiple devices without restrictions

Subscribe to shared or public collections to receive card updates

Share your cards with friends, family members or students

Easily create your own cards from camera, text or images

How it works

Our spaced repetition algorithm monitors your progress with every card, automatically adjusting the timing for optimal learning.

With each correct answer, the interval and difficulty level increase, while incorrect answers shorten the review period and decrease difficulty level. The intervals range from a few minutes to years.

You can also choose to focus on particular collections or even cram cards outside the regular spaced repetition schedule — giving you complete control over your learning experience.

Science

What about it?

Learning new words can be challenging and requires effective tools. That's why we created Kortz — to help you memorize new words efficiently. To achieve this, we incorporated key scientific principles of effective vocabulary learning and conducted a detailed analysis of more than 50 other flashcards mobile applications. We distilled our findings into a set of criteria that no other platform fully met. Kortz is built on this foundation.

Memory and Repetition

Ever wondered why you can remember a telephone number for years but struggle with a random seven-digit number? Our app understands the science behind it – the transition from short-term to long-term memory through repetition.

Forgetting Curve

Forgetting curve, suggests that newly acquired knowledge diminishes without conscious review. Hermann Ebbinghaus' work emphasizes that each repetition increases the optimal interval before the next review. Kortz uses incremental algorithm to manage the spaced repetition.

Testing Effect

The testing effect, also known as retrieval practice, is a cornerstone of our app. By dedicating part of the learning period to retrieving information, our app maximizes long-term retention. Repeated testing has proven to outperform repeated studying, and the app employs spaced repetition to enhance the testing effect, creating lasting connections in memory.

Spacing Effect

The spacing effect highlights the power of spaced-out study sessions. Cepeda et al.'s study (2006) demonstrated that spaced practice consistently outperformed massed practice in memory tasks. You can read more about scientific learning about the advantages of spacing effect over cramming here. You can also cram cards with Kortz.

Feedback and Desirable Difficulty

Getting feedback is pivotal, and our app seamlessly integrates it. Determining a desirable difficulty level for tests, combined with feedback, ensures an optimal learning experience. Accessing your knowledge, our app tailors the learning process, surpassing passive studying or testing without feedback. The app adapts by increasing the complexity of challenges as you progress through the learning journey, ensuring a tailored and focused language learning experience.

Spaced Repetition Mechanism

Our app employs a customized implementation of the Leitner System, a proven spaced repetition mechanism, ensuring optimal learning. It integrates seamlessly with your diverse learning resources, becoming a valuable ally in your language learning journey.

Owning your Library

Learning superfluous information can contribute to retrieval-induced forgetting, as explained here. Your mission is to curate relevant content with the assistance of other language apps, books, videos, daily experiences, and more. This approach ensures that the app delivers a concentrated and personalized language learning experience.
