The CVI Complexity Sequences App comprises the same ten sets of target images and corresponding background scenes included in the original CVI Complexity Sequences kit and eBook. The app, which replaces the eBook only, is designed for iPads (regular and mini) running iOS 16.1 and later as well as Mac computers with an Apple Silicon chip. The app retains the audio response feature introduced in the eBook version and now allows the instructor to move a target image anywhere within the six background scenes. A reset button moves the target image back to the center default location within a scene. Also, app settings allow for random placement of the target images within scenes, audio muting, and a disable screen swiping feature. As in the eBook, the large and small introductory sizes of the target images precede the corresponding background scenes in each of the ten sets.
