At his first Olympic Games, the 2020 Summer Olympics in Tokyo, Japan, Apple competed in the prelims and the final of the 4x100-meter freestyle relay. In the final of the event, Apple swam the fastest of any of his relay teammates, splitting a 46.69, which was over half a second faster than the next fastest relay swimmer Caeleb Dressel. The finals relay of Apple, Caeleb Dressel, Bowe Becker, and Blake Pieroni finished first in a time of 3:08.97, with Apple anchoring the relay. All relay teammates, including prelims-only swimmer Brooks Curry, won the gold medal for their efforts. Apple was the first athlete from the Auburn University swim program, past or present, to win a gold medal in swimming at an Olympic Games since the 2012 Summer Olympics.
