Learn Sheet connects to your Google Sheet and turns whatever you put in there — vocabulary, exam terms, or other facts — into spaced repetition flashcards. It’s especially handy for language learners. You keep adding words and phrases to your spreadsheet, and whenever you open the app, it pulls in your latest updates and shows you cards to study. No need to mess with decks, complete quests, or talk to an AI tutor. Just your sheet, and a straightforward way to remember what's in there.
