Whether you have an event you are excitedly waiting for or a deadline you want to be sure to remember, the Countdown App may be for you. Created by Time and Date, a Norwegian company that produces numerous calendar related tools and phone applications, Countdown is a relatively straightforward tool. Users simply enter an event along with a date and time, and Countdown will reveal the days, minutes, and seconds until that event. Visitors can select a thematic background to accompany their event by either choosing one of the pre-made themes, such as Birthday, Vacation, and Tax Day, or by uploading a custom picture. Countdown is available for both iOS devices and Android devices.
