With Day Zero you keep up with events in your life. Events that matter to you such as birthdays, holidays, anniversaries, weddings, and more.

Customize each countdown by adding a background from Day Zero's incredible library or by adding a photo from your own library. Get notified when a countdown passes, see how many days it has been since the event has passed and share your countdowns with friends on Facebook, Twitter, Instagram, and more.

With Day Zero on the Apple Watch you can quickly glance at your countdowns while on the go, use Day Zero as a complication and always stay up-to-date on your events.

You can now use Day Zero's Today View Widget to quickly your upcoming countdown events.

What's New

Keep improving


A clean and nice interface that’s easy to use. However, there are a few things that could improve the app. The widget displays the older events that have already passed so there’s no way to view upcoming events. I assume it’s going by the top three events in the app which leads to a second issue. It would be great to sort events within the app to have new events at the top. Also, the feedback option in the app doesn’t work. Hope these are considered for future updates.

Nice clean interface


Simple, easy to use. Clean interface, nice stock photos. Less glitzy than other apps in this category which I appreciate. Have not tried with My Apple Watch, so cannot comment on this functionality.

Not worth the $


Pictures did not show up on Apple Watch. Also did not show up as a complication. Paid for the full version and now fully disappointed.
