Positioning
Anki is the gold standard for spaced repetition, using an open-source algorithm (SM-2) that lets users create and share decks. Its strength is extreme customizability via add-ons and card templates, but the manual card creation process is tedious. Free on desktop; iOS app costs $24.99 one-time.
