A possible concise summary is:
Mark, Ethan and Tyler play the 7 Second Challenge app by Dan and Phil, but they get frustrated by the repeated and outdated challenges. They try a knock-off app that gives them nine seconds instead of seven, but it's even worse. They make fun of each other's attempts to do impressions, exorcisms, and dog barks, and they ask for fanart of Xyler, Mark's evil twin. They end the video by asking Dan and Phil to update their app and thanking their judges Amy and Kathryn.

- The app has not been updated by its creators, Dan and Phil, so they encounter many duplicates and glitches.
