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.

Verdict
The clearest difference is in-app purchases: KKUK at none against PlanRight's 2. PlanRight's advantage is ads (none vs shown). On price, review sentiment, update cadence and monetization model there is nothing between them.
