You wouldn't find it on iPhone X, since Move to iOS is an Android application.
Depending upon what you want to transfer Android File Transfer might get the job done. I've used it to recover various media files from some of my friends phones. It's pretty easy to run.
I know that Android File Transfer is for moving files to the computer. Unfortunately, I didn't explain the next part clear. Once the files are in the right place on the computer they can then be moved to the iPhone by following the normal procedures to transfer files to the iPhone.Thanks, mods. This app is for data transfer between Android and computer, not Android to iPhone. I hope all data on Android to be moved to new iPhone.
