CLUSTER LEARNING-REPETITION-SPACED · 28 ENTRIES · EARLIEST ENTRY 2026-08-11
Spaced repetition vocabulary apps
This cluster comprises web apps for learning vocabulary through spaced repetition, with users adding words and reviewing them on a schedule. Entries are sporadic from May 2021, with a denser stretch in early-to-mid 2026, though the overall dated history is limited. On traction, wordbook-worker leads with 1 star, while lingo-fox and vocab-loop each have 0 stars.
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.
