If you prefer to play the slides with another app, use the export Slides button.This creates a .zip archive with .png images. Those images can be used in almost all presentation apps. Open a slide and use the command to import media.

Some presentation apps allow you to select all the images and automatically create a slide per image.
For example, this is how it works in KeyNote (Mac):

  1. Open a new document in with Apple’s KeyNote.
  2. With Finder open the folder with all .png images.
  3. Select all images (Command A) and drag and drop the images into the KeyNote navigator (left side)
  4. Optional: Select all slides and change the master (right side) to “Blank”
    Import into Keynote

Do you use another app? Please check the help of that app for instructions.
