Habit Stamp Book

Build your daily routine one stamp at a time. Habit Stamp Book is a simple habit tracker inspired by the Japanese hanko — the personal stamp used in Japan to sign and approve. Every time you finish a task, you press a red “済” stamp, which means “done” in Japanese. Watch your calendar fill up with stamps and see your progress add up. ■ A stamp that feels real Tap the circle next to a task to press the stamp. A satisfying sound and a solid haptic thud make every small win count. Finish everything for the day and a big stamp celebrates with you. ■ Make it yours with themes Choose stamp colors (vermilion, indigo, sumi ink, gold), marks (済, 完, 良, double circle, check, DONE, GOOD), papers (washi, sakura, night sky, seigaiha waves, matcha), and sounds (bell, taiko drum, wooden fish, temple bell). Try them on before you decide. Finish all your tasks on 7, 14, 21, and 28 days to earn themes for free. ■ Your days, your pace Pick which days each habit shows up — gym on Monday and Thursday only, for example. Couldn’t do it today? Move it to tomorrow. It won’t count against today, so finishing the rest still makes today “all done.” ■ See your progress add up - A monthly calendar shows how much you did each day - Fully finished days get a stamp - See how many days you’ve finished everything this month - A short note at the end of each month looks back on how it went - “By Task” shows which habits stick and which ones slip - Forgot to stamp? Fix past days anytime ■ A note for today Leave a short note about your day — lighter than a journal. ■ Widgets Stamp tasks right from your Home Screen or Lock Screen without opening the app. ■ Daily reminder Get a reminder at the time you choose. No reminder on days when everything is already done. ■ Calm, Japanese-inspired design Washi paper tones and hanko motifs. Dark mode supported. ■ Privacy No account needed. Your records stay on your device. * The app shows ads. “Remove Ads” (one-time purchase) hides banner ads. Themes are available for free, as rewards, for a day by watching a short ad, or all at once with the “Theme Pack” (one-time purchase).
