Built so the date is the loudest thing on the widget.

One number, one name. The small widget is free. Medium, large and Lock Screen widgets come with Premium, along with your own fonts, colors and photos.

Open the app and your dates are the first thing you see.

The top shows how much of the week, month and year is left. Below it, count-ups, countdowns and birthdays, each led by its number. Lay them out four ways.
