It took more time and effort than hoped, but PhotoPresenter is now ready for iOS 11 and available from the App Store.
PhotoPresenter is the perfect solution for showing you photos if you don't have time to prepare a slideshow. The photos in your library are invisible to the audience until you tap on them to make them appear on your external screen. PhotoPresenter supports all kinds of photos and videos in your Photo library. A Laser Pointer feature helps you to highlight specific areas of your photo and you can use your own logo to brand the screen that is shown if no photo or video is selected.
