Jibun ni Kiku is a daily reflection app where you write your own answer to one question each day — and your answers stay entirely on your iPhone. A quiet space in the middle of busy days, where you can sit with your own thoughts. The library currently spans 180 questions across 10 themes, with a new question arriving every morning. There are no right answers. Nothing here is for anyone else to see. No cloud sync, no external servers. No ads, no tracking. Your honest answers belong to you alone. Face the question, slowly write your answer in your own words. That's all the app does. The first 7 days are free. After that, ¥980 unlocks full access (one-time purchase, no subscription).
