See Apple Calendar events and Reminders together in one clear timeline. Timelane helps you see what is happening now, what still needs attention, and what comes next. Keep using your existing calendars and reminder lists, with a focused view of the day ahead. YOUR DAY, ASSEMBLED See overdue work, today’s events and reminders, and the days ahead in one continuous timeline. Move through dates naturally, complete reminders where they appear, and keep the day in context. A PLACE FOR UNDATED TASKS Reminders without a date stay visible in Needs Scheduling until you decide where they belong. Nothing disappears simply because it has not reached the calendar yet. CALENDAR AND REMINDERS STAY IN CHARGE Timelane works directly with Apple Calendar and Reminders. There is no separate account to create. Your information remains available in Apple’s apps and syncs through the services you already use. BUILT FOR ALL YOUR SCREENS • iPhone and iPad keep the full timeline close at hand • Mac gives the day more room to breathe • Apple Watch shows what is next and supports quick task entry • Home Screen widgets keep the timeline and calendar visible • Apple Watch complications surface upcoming items at a glance THE DETAILS WITHOUT THE OVERHEAD Choose which calendars and reminder lists appear. Create and edit events and tasks. Keep repeating reminders useful, see today’s completed items, set optional notifications, and mark important reminders as deadlines. PRIVATE BY DESIGN Timelane does not collect your calendar events or reminders. It reads and updates the Apple databases on your devices only with the access you grant. Productivity should not become another project. Timelane helps you see the day clearly, handle what matters, and move on.

A to-do list erases what you finish. KKUK does the opposite — every day you follow through leaves one more stamp. Press one stamp today. Then watch them stack up on the calendar. ■ 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. ■ 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. ■ 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 — set all of it per stamp. ■ See what you've kept · Calendar — every stamp you pressed this month on a single board. · Journal — leave a note and a photo beside the stamp. · Report — 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. · Monthly review — look back on the month that just ended. ■ Seven Home Screen widgets Today's Stamps · Recent check-ins · Calendar · Weekly report · Monthly report · Group weekly · Large calendar. Pick any size and keep it on your Home Screen. ■ Make it yours Twenty bundled typefaces — four drawn for Latin text, sixteen Korean. Light, dark, or follow your device. Portrait only. ■ Free to use 3 stamps, 3 groups, the last 30 days of records, this week's and this month's report, and the Today's Stamps widget. Watch a rewarded ad all the way through to add one more stamp, and the slot you earned stays yours. ■ KKUK Premium unlocks · Unlimited stamps and groups · Every record, including anything older than 30 days · Past reports and past monthly reviews · All seven widgets · iCloud sync to continue on another device · No ads ■ Subscription details · KKUK Premium Monthly — $1.99 / month · KKUK Premium Yearly — $12.99 / year Subscriptions renew automatically.

Terms of Use https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy https://kkuk-app.web.app/en/privacy/ ■ Your records stay on your device Stamps, notes, and photos are stored on your device.

Verdict
The clearest difference is price: KKUK at Free against Timelane's $0.99. KKUK also leads on update cadence (every 4 days vs fortnightly) and iOS requirement (18.0 vs 26.0). Timelane's advantage is ads (none vs shown) and device support (4 vs 2). On in-app purchases there is nothing between them.
