First of all, they did copy Dan and Phil.

This app may have been made first, but Phil did invent this challenge. They just recently made an app for it. Many youtubers did the seven second challenge before the app was made. But, still, Phil made it first. Just because they just now made an app for it doesnt mean whoever beat them to the punch to making an app for it doesnt mean they are the inventors. Seriously, do your research.

You all are stupiddddd about Seven Second Challenge!
