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. PRIVATE BY DESIGN Your events are kept on your devices and in your own iCloud, where only you can read them.

Verdict
The clearest difference is in-app purchases: Countdown at none against ChainASC's 2. Countdown also leads on update cadence (every 2 days vs every 9 days). ChainASC's advantage is iOS requirement (17.6 vs 26.0). On price, ads and device support there is nothing between them.
