Google Slides now supports Chromecast and AirPlay

Today’s update to the Google Slides app makes it even easier to share presentations on big screens. With just your phone or tablet and the Google Slides app, you can present easily to any screen with Chromecast or AirPlay.

When you’re presenting on the big screen, you can use your smaller screen to advance slides, view speaker notes and stay on track with a timer. This way you can focus more on telling your story and engaging your audience, instead of on logistics.
