You can check if some features, like VoiceOver, are on. Experiences should not diverge too much.

If your app lets the user share images, consider implementing the possibility for them to add an alt text for the image, so it can be used as an accessibility label when consumed by other users. Twitter or Slack have nice flows for doing this.
