The list updates regularly to reflect changes in interaction frequency, showing up to eight of your closest contacts. Snapchat uses emojis next to each name to indicate Snapchat best friends list different levels of interaction, such as the "????" (Smile) emoji for a close friend, or "❤️" (Heart) emoji for a best friend, making it a fun and convenient way to track your strongest connections.
