CLUSTER FLASHCARD-REPETITION-SPACED · 58 ENTRIES · EARLIEST ENTRY 2009-03-27
Spaced repetition flashcard apps
This cluster consists of flashcard apps built around spaced repetition, serving niches from exam prep (MCAT, law, pharma, FINRA) to language learning and general study, with common features like offline access, deck import/export, and sync. The dated entry record runs from March 2009 through June 2026, showing mostly single entries per month with occasional pairs, never more than two in a month before the index start—a steady but low-level trickle rather than any pronounced pattern. Traction leaders are all at zero stars (Flashcards · Baro, Ancurio: AI Flashcards, FSRS Mobile · Flashcards), indicating negligible user activity across the cluster.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
