SpellWise: Korean Spelling

Is it "되요" or "돼요"? "왠지" or "웬지"? Korean spelling rules trip up even native speakers all the time. SpellWise turns those tricky spots into a daily 10-question quiz so you can nail them for good.

This isn't a grammar-correction tool that fixes sentences for you — it's a quiz app built to help you actually understand the rules, one short session at a time.

Key features

- Daily 10 questions: a fresh quiz set every day, plus a streak counter to keep you coming back.
- Multiple-choice quizzes: pick the correct spelling in a fill-in-the-blank sentence and get instant feedback with a one-line explanation card, so you understand exactly why an answer is right.
- Practice mode: choose a category (spelling, spacing, confused vocabulary) and one of three difficulty levels, then practice at your own pace.
- Wrong-answer notebook: missed questions are automatically saved so you can retry them until you truly master them.
- Streaks & stats: track your daily streak, overall accuracy, and per-category performance at a glance.
- 300+ built-in Korean spelling, spacing, and confused-word questions — no network connection required to play.
- Switching to English mode doesn't just translate the UI — the question set itself switches to English confused words like their/there/they're and affect/effect, so English speakers get the same learning experience.
- No sign-up or login required. All your progress is stored locally on your device.

Great for
