Never lose a draft or a streak again. Reminders now know when you've already played, and today's puzzle opens instantly — even offline. Master the subtle differences between English words — one pair a day. DailyDiff gives you two easily confused words every day (like Begin vs Start), each with a clean black-and-white illustration. Your job: explain, in English, how they really differ. An AI then scores your answer across five dimensions and reveals the model answer — so you learn something precise every single day. WHY DAILYDIFF • One focused puzzle a day — no endless feeds, no overwhelm • Write freely; get specific AI feedback, not multiple choice • Five-dimension scoring: accuracy, coverage, language, clarity, insight • A clear model answer with definitions, key differences, examples, and common mistakes • Build a daily streak and share a no-spoiler result card Perfect for English learners, ESL / TOEFL / IELTS prep, writers, and anyone who loves the nuance of words. One subtle difference a day. That's all it takes.

- Daily reminders, rebuilt: your nudge now names the streak you're protecting, and stays quiet on days you've already played. - Fixed the reminder switch looking on while no notification ever arrived — turning it on now tells you when notifications are blocked, with a shortcut to Settings. - Your answer saves as you type: step away to look a word up and come back to find it waiting. - Added a Done button above the keyboard, and you can now swipe down to dismiss it. - Today's puzzle opens instantly and stays readable offline, including your own result for the day. - The word-count hint now matches what Submit actually asks for.
