How do I show the slideshow on a TV?

Choose Play slideshow, then tap the AirPlay or Google Cast icon. Use AirPlay / Screen Mirroring with a compatible TV, or Google Cast with a Chromecast / Google TV in the iPhone test app.

iPhone: AirPlay / Screen Mirroring

Your TV needs AirPlay support or a connected Apple TV box.

Connect your iPhone and TV to the same Wi-Fi.
Swipe down from the top-right corner of your iPhone to open Control Center. On an iPhone with a Home button, swipe up from the bottom.
Tap Screen Mirroring (two overlapping rectangles), choose your TV, and enter any code shown on it.
Return to the slideshow, turn your phone sideways, and keep it open and awake.

To stop, open Control Center → Screen Mirroring → Stop Mirroring.

Compare TV connections

Swipe across the table on smaller screens.

For live updates, keep the live slideshow open and connected to the internet. When mirroring or using HDMI, keep the source device awake. New photos appear after approval, if required.

Downloaded videos include only the photos present when you make them. Export a new video to include later additions. TV, adapter, and video-format support vary by device.

Add to your home screen

Save an icon that opens Slideshow Ninja like an app. Open the home page or dashboard before installing, so your icon opens the main app.

iPhone or iPad: In Safari, tap Share, then Add to Home Screen. Turn on Open as Web App if shown, then tap Add.
Android: In Chrome, tap More (three dots), Install and create shortcut, then Install. Some versions show Add to home screen or Install app.
