Four judges. Thirty seconds. One golden buzzer.
Play it on a speaker, TV or smart speaker so the camera hears it.
Filming with a second phone or tablet? Then this phone can play the music.
Use your Camera app in Video mode so the dance saves to your Photos. Get the whole dancer in the picture, dance the full 30 seconds, and finish with a freeze pose.
Filming it now is quicker, but that video will not be kept in your Photos.
Grown ups: inside Claude this phone cannot film and play music at the same time, so the judges watch a recorded tape. When the game is opened from its own web address, this phone plays the music and records the dance together, with a countdown and freeze breaks.
