I've been seeing a lot of misinformation so:
| Word | Meaning |
|---|---|
| App | A Bot account on Discord, always has the "APP" flair |
| Server App | A Bot account with support to be added to Servers, so all the Server's members can use it |
| User App | A Bot account with support to be added to User accounts, so that User can use its commands in across Servers & DMs/GroupDMs |
