A crisp, succinct sound unfolds as the title suggests an "App Button Click". The audio captures the essence of an action being performed, a button being pressed. It's reminiscent of the subtle bleep noise often heard in animations or cartoons, providing a sense of acceptance of the action performed. It could easily be associated with a chat app, where each message sent is accompanied by this satisfying click. The sound is well-designed, it's not jarring or overly loud, but rather a comforting confirmation of a task being completed.
