Countdowns is a simple app that lets you keep track of the number of days left for an event to happen. The app helps set reminders for any number of personal and/or official events. You can view them individually or all by a single swipe. Notifications come through when the date is nearby or fast approaching. You could choose to count down in days and even hours or minutes. Equipped with a clean and simple user interface, the widget supports iCloud sync with all your Apple devices. And the best part is there are no ads.
