ATO

Anniversaries and countdowns.

Counts the days since a moment and the days until the next one, with milestones made for you. You can also log when you last did something, and share the count as a poster.

Countdowns can repeat every year or month, and events can come from Calendar or Contacts. Widgets and Live Activities keep the count on the Home Screen and Lock Screen.

Everything is stored on the iPhone, with no account. Pro is a one-time purchase, and iCloud backup writes to your own iCloud Drive.
