Anki is a flashcard application built around spaced repetition, using an algorithm to schedule reviews so learners spend more time on challenging material and less on cards they already know well. It is free and open source on desktop (Windows, macOS, Linux), with source code publicly available on GitHub and an extensible add-on ecosystem built by the community.
Drops teaches vocabulary in over 40 languages through short, icon-driven games rather than grammar drills, pairing each word with an illustration to build recall through visual association and spaced repetition. The free tier caps sessions at 5 minutes a day, a deliberate constraint meant to build a daily micro-habit instead of encouraging long study blocks.
