There are many free countdown apps for watches available online. Many of the apps not only sync between a watch and other products, but also share messages on social media sites.
Many apps come with pre-installed events and allow users to add and alter personal events. Extra features often include timers and the ability to set recurring events, review past events. iTunes identifies which apps are available for the iWatch. Dreamdays Lite is one such example, and the app includes a widget, voice memos, and push notifications. Google Play also offers many watch apps for Android products. As of 2015, watches made by Moto, LG, Sony and Samsung can use Countdown, which includes event countdowns and weather forecasts.
