The idea here is, these are apps that will have a watch app on day one. I expect Apple is going to drop iOS 8.2 next week, so these apps will already be on your phone, with the watch binary, waiting for the day the watch jumps on your wrist.
I have a few duplicates just for filler. If you have any suggestions, feel free to submit them or let me know here.
AFAIK Apple is not accepting apps with Watch binaries? (You still need to use the beta version of Xcode to create Watch Apps & Apple does not review apps built with beta versions of Xcode)
