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 32 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. Unless canceled at least 24 hours before the current period ends, a subscription renews at the same price, and payment is charged to your Apple Account at confirmation of purchase. You can manage or cancel subscriptions in Settings > Apple Account > Subscriptions on your device. 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. There is no account and no sign-in. iCloud sync is off by default, and when you turn it on, records are copied only to your own private iCloud database. The developer cannot read them and does not keep them on a separate server.
Compose AI Executive Assistant

Your inbox, run like an executive assistant runs it. Compose is built for Gmail and Google Workspace accounts. It reads your email, tells you what needs you today, keeps a live ledger of what you promised and what you're waiting on, and drafts the reply — so you decide and move on. Outlook and IMAP accounts are currently not supported. KNOW WHAT NEEDS YOUR ATTENTION Compose continuously analyzes your email and surfaces: • Urgent messages • Top priorities • Risks and important developments • Direct asks that need a response • Commitments you have made • Things you are waiting on • Follow-ups that may otherwise fall through the cracks Instead of treating every email equally, Compose helps you focus on what actually requires your attention. YOUR EXECUTIVE DAILY BRIEF Get a real-time view of: • What is urgent • Your highest-priority conversations • Important commitments, asks and waiting-ons • Upcoming calendar events • Tasks and follow-ups See the state of your work without reconstructing it manually from your inbox. TRACK COMMITMENTS AUTOMATICALLY Compose identifies commitments inside email conversations and maintains a live ledger of what you promised, what others asked of you, and what you are waiting for. As conversations progress, their status can update automatically — helping prevent important obligations from disappearing into old threads. AI THAT HELPS YOU ACT Compose goes beyond summarization. From the context of an email, it can help you: • Draft replies • Generate responses in your voice • Create tasks • Schedule meetings • Add follow-ups • Determine appropriate next steps • Trigger connected workflows The goal is simple: move from reading → deciding → acting with less friction. EMAIL INTELLIGENCE, NOT JUST EMAIL Compose is designed around a different question: Not “How can AI help me write this email?” But: “What does this email mean for my work, and what should happen next?” For founders, executives, managers, consultants and professionals whose inbox is also where decisions, obligations and follow-ups live.
