Space Repeat review
A free web study app for active recall, adaptive reviews, and vocabulary practice.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Space Repeat is a web-based study app for learners who want to retain material through active recall and spaced repetition. Users create question-and-answer decks, review cards, and rate their difficulty so the app can adjust review timing. Its vocabulary builder adds a separate workflow for word lists, making it relevant to learners who want vocabulary practice alongside general study cards.
The free plan is the only described plan: it costs $0 and includes the spaced repetition algorithm, retention statistics, and unlimited reviews. The homepage describes limits of 50 decks, 100 cards per deck, and 400 vocabulary words. Vocabulary lists can be imported or exported as CSV or TXT, and optional pronunciation audio and example sentences support word study. Folders, color-coded tags, multiple study modes, a Pomodoro timer, and Blurt Mode add organization and ways to structure individual sessions. That scope suits solo learners and small-scale study, rather than a shared-deck workflow.
Its main trade-off is narrow platform coverage: Space Repeat is web-only, with no mobile apps or shared decks. The difficulty-based scheduling, retention statistics, and separate vocabulary schedules are a focused set for learners who want to manage their own review routine in a browser. Those looking for mobile study or to use decks shared by others should choose a tool with those capabilities. For a web learner concentrating on vocabulary and active recall, the free plan offers a straightforward way to organize and revisit study material.
