Snapchat, launched in 2011 as a photo messaging app, became known for its distinctive short alert tones as smartphones replaced ringtones with app notifications. This version circulated widely in 2019, when users recorded and shared the chime outside the app for pranks and edits. Its popularity comes from instant recognition - most listeners have heard it from a friend's phone in class, at work or on public transport. That familiarity keeps it in use as a joke alert, a transition sound and a nostalgic reminder of late 2010s social media.
