Win

Win is a flexible flashcard learning app that supports multiple subjects and difficulty levels, making it suitable for complete beginners and advanced learners alike. Beginners can start with the Basic English deck (100 cards), the largest in the app, while more advanced users can challenge themselves with the Advanced English deck (50 cards) packed with nuanced vocabulary and idioms. The spaced repetition system ensures you never waste time re-studying words you already know. Cards are rated 0–5, and only those below level 4 are regularly surfaced, letting you focus your energy where it matters most. Win's review mode takes this further by showing only cards at levels 0–3, the ones that genuinely need reinforcement, so your study time is always pointed at real gaps in your knowledge. No account, no fees, no internet. Win stores everything on your device and is ready to help you learn from the moment you install it.
