## What is DueMark?

Some dates are worth looking forward to. Others are worth keeping close.

DueMark gives your important days a calm, welcoming home. Count down to a birthday, wedding or trip, and count the days since a moment that changed your life.

COUNT DOWN AND COUNT UP
See how many days remain or how many have passed. Pin the events that matter most so they are easy to find.

YOUR MONTH AT A GLANCE
Browse events and holidays in the calendar. Create events using lunar dates as well as regular calendar dates.

IMPORTANT DATES, ALWAYS CLOSE
Use Home Screen and Lock Screen widgets to see important dates and upcoming events at a glance.

MAKE IT YOURS
Organize events in notebooks, choose repeat rules and set reminders. Start with event templates and use the date calculator to work out the time between dates.

REMINDERS WITH A FAMILIAR SOUND
Set reminders and push notifications for important events. Choose or record a custom notification sound to make each reminder feel more personal.

ADD EVENTS WITH SIRI
Create events with Siri as important dates come to mind. Keep them in view with the calendar and Home Screen and Lock Screen widgets.

ON THIS DAY
Explore events from history that happened on this date, alongside the moments in your own life.

FREE ACCESS AND MEMBERSHIP
The free version offers basic functionality with limits on event counts, reminder counts, push reminders and app icon changes. Membership unlocks all features and removes these free-version restrictions. Weekly, annual and lifetime plans offer the same feature access.

IN-APP PURCHASES
• Weekly membership: an auto-renewable subscription billed every week, with a 3-day free trial for eligible users.
• Annual membership: an auto-renewable subscription billed every year, with a 7-day free trial for eligible users.
• Lifetime membership: a one-time purchase for permanent access to membership features, with no automatic renewal.

Prices and trial eligibility are shown in the app and Apple's purchase confirmation. Unless canceled, a trial converts to a paid subscription at the displayed price for the selected plan. Payment is charged to your Apple Account at purchase confirmation, or after the free trial if eligible. Subscriptions renew automatically; renewal is normally charged within 24 hours before the current period ends. Cancel at least 24 hours before the current period or trial ends to avoid renewal. Manage or cancel in Settings > Apple Account > Subscriptions. A lifetime purchase does not cancel an existing subscription; cancel it separately. Notifications require system permission.
