What is what does it mean when someone's snap score goes up by 1?

A Snapchat score is a combined number representing your activity on the app. When your score increases by one, it typically means you've either sent or received a Snap.

Here's a breakdown:

• Sending Snaps: Each Snap you send to a friend usually adds one point to your score.
• Receiving Snaps: Each Snap you receive from a friend also generally adds one point to your score.
• Other Factors: Other activities such as posting Snapchat%20Stories and other unspecified factors also contribute to the total score. Just because your score goes up by one, it doesn't mean you definitely just sent or received only one snap.
