Days until the dates you care about: on your Home Screen and Lock Screen. Every feature is free: every widget, every reminder, iCloud sync, all 123 icons and 12 colors. No subscription, no in-app purchases, no ads, no account, no tracking. Add an event, pick a date, and see one big number: the days to go. On the day it reads Today. Afterwards it counts up. EVENTS • A name, a date, one of 123 icons and one of 12 colors for each event. • Birthdays and anniversaries can repeat every year, so they always count down to the next one. • Upcoming events first, soonest at the top. Past events in their own section. • Whole days only. The count changes at midnight, wherever you are. WIDGETS • Small: one event in its own color. Pick the event, or let it follow your next one. • Medium: your next event, and the two after it. • Large: your next six events. • Lock screen: circular, rectangular and inline, each for one event. • Tap any event in a widget to open it. REMINDERS • Choose any of six for each event: on the day, 1 day, 3 days, 1 week, 2 weeks or 1 month before. • They arrive at the time you set, 9:00 AM to begin with. • Tap a reminder to open its event. IPHONE AND IPAD • Events sync through your own iCloud. There is nothing to sign in to. • Add an event on one device and it appears on the other. • Without iCloud, everything still works on the device.
