Flashcards in Space

Flashcards in Space is a fun and efficient spaced repetition system that helps you learn vocabulary or any other concept you can put into flashcards. Built with a space-themed UI, humor and powered by a custom Lightspeed Schedule algorithm.

🎯 Motivation

Existing spaced repetition tools often prioritize function over form, resulting in dated interfaces that can make daily practice feel like a chore. Flashcards in Space was created to bridge this gap, combining proven learning science with a modern, engaging user experience.

At its core is the Lightspeed Schedule, a custom spaced repetition algorithm designed to optimize retention while keeping sessions efficient. Built on the foundational research of Hermann Ebbinghaus, Sebastian Leitner, and other pioneers of spaced repetition science.
