This app is a Countdown app for Developers. This app is a Countdown app for Developers. You can follow the flow of time directly in the notification center with the widget with a graphic similar to the app one.
You can also share the countdown with the button on the top-right. You will share also the screenshot of the view.
This app is not only a countdown. When the countdown finishes, you can see the Live directly from the app, and if you have an iPad, you can watch it while you are using an another application with the new feature PiP.
With rich notifications, the experience would be awesome (requires iOS 10.3). And with the Taptic Feedback, you will enter in the live! (requires iPhone 7 or 7 Plus)
And when the live finishes? You can watch the live another time, read most important new features posts from Gilles, or download the WWDC App, to stay update on the news from the biggest Developer Conference all over the world.
