A to-do list erases what you finish. KKUK does the opposite β€” every day you follow through leaves one more stamp. Press one stamp today. Then watch them stack up on the calendar. β–  Press it without opening the app Open the app once and today's board appears on the Lock Screen and in the Dynamic Island. For a while after that you can press a stamp right there, without going back to the app. You can also press one from a Home Screen widget. β–  A press, not a tap One quick tap won't do it. Hold your finger until the ink fills all the way, and the stamp lands. Slide your finger aside to cancel a press you didn't mean. β–  Make your own stamp Build a stamp from 16 colors and an emoji. Which weekdays, how many times a day, which group it belongs to, and when it should remind you β€” set all of it per stamp. β–  See what you've kept Β· Calendar β€” every stamp you pressed this month on a single board. Β· Journal β€” leave a note and a photo beside the stamp. Β· Report β€” see how well you kept up by week, by month, and by year. The period you're looking at can be exported as a CSV file. Β· Monthly review β€” look back on the month that just ended. β–  Seven Home Screen widgets Today's Stamps Β· Recent check-ins Β· Calendar Β· Weekly report Β· Monthly report Β· Group weekly Β· Large calendar.
