About Vocabulary Builder by Knudge
Knudge is a vocabulary app from Knudge Technology, which has been making word apps since 2016. It is built around short, five-minute sessions: you learn hand-picked words with definitions, example sentences, synonyms, antonyms and visual cues, then review them with adaptive flashcards and revision tests that bring each word back just before you'd forget it. Words can also arrive as notifications at a frequency you set. Lists run from everyday English to advanced exam vocabulary for the GRE, SAT, GMAT, TOEFL and IELTS, and there are courses on idioms, phrasal verbs and commonly confused words. More than ten games cover spelling, reading, comprehension and grammar, and it works offline. It suits students preparing for exams and working adults who want a short daily drill with more variety than a single quiz format. The trade-off: despite being listed as free, most of the app sits behind a subscription after a short trial, which some reviewers found unclear up front, and the App Store listing mixes old and new purchase options. The Android version is now marketed more broadly as an English-improvement app with grammar, so it leans toward English learners as much as native speakers.
Best for: Exam takers and busy adults who want five-minute daily drills with varied word games.
