How we picked
Each app covers at least one study need: notes, flashcards, homework help, essays and citations, exam revision or book summaries. Each has a free plan or free tools. Seven come from companies founded in Europe. We added Quizlet, which is US-based, because a list of study apps without it would leave out the app most students start with.
We compared official facts: prices and plan limits from the companies’ own pages and app store listings, checked on 6 October 2026, and our company profiles. We did not test the apps ourselves. StudyGo and Memrise appear in our Quizlet alternatives list; StudyGo serves Dutch schools, and Memrise teaches only languages.
