What is what does it mean when there's a green dot on snapchat?

A green dot on Snapchat typically indicates that a friend has been recently active and is likely available to chat. It essentially means the user is currently online or was very recently online. Seeing a green dot makes it a good time to send them a <a href="https://www.wikiwhat.page/kavramlar/Snapchat%20message">Snapchat message</a>, as they're more likely to see and respond to it quickly. It doesn't necessarily mean they're looking at your profile or even using Snapchat at that exact moment, but rather that the app is open in the foreground or background on their device. The absence of a green dot doesn't mean the user isn't using Snapchat, it just means they haven't been active recently enough for the indicator to appear.
