Based off of a game AmazingPhil created, the 7 Second Challenge was an app, developed by Mind Candy LLC. It was released to Apple and Android. It was discontinued in 2018. At one point, fans were able to suggest new ideas for challenges, which were implemented into the app. Phil explained in the below video that the idea for the app came around when he made a video with KickThePJ where he played a version of the game before the app as a fun collaboration idea!
