CLUSTER PRACTICE-THROUGH-VOCABULARY · 57 ENTRIES · EARLIEST ENTRY 2025-03-19
Vocabulary learning web apps
This cluster consists of web and PWA applications focused on vocabulary acquisition, primarily for English and Spanish learners, using spaced repetition, flashcards, quizzes, and progress tracking. Dated entries appear sporadically from 2014, with a single entry in 2014, a gap until 2020, then entries in 2021, 2023, 2025, and a few more in early 2026, though most members lack source dates. Traction leaders are Vokabel (3 stars), wordbook-worker (1 star), and loop-vocabulary (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.
