Building on your feedback, it is now easier than ever to add pictures, videos and text to your Sway. Previewing your creations is also quicker than before—simply switch between Edit and Preview at the top to see the polished and cohesive design taking shape as you create.

Sway for iPad is optimized for the larger screen. It allows you to create, view and share Sways in landscape and portrait mode and also includes a few additional capabilities, such as the Remix! button for quickly trying out different layouts and styles. Now is a perfect time to download or update Sway for iPhone and iPad from the App Store today!"
