Kim launched Kimoji's Monday -- Kim-themed emojis -- and the response was crazy. So many people tried downloading it at once, the Apple app store couldn't handle the tidal wave and started crashing.

At one point today it was getting 9,000 downloads per millisecond. 

We're told the Apple tech team swooped in and shored it up so it didn't fully crash.

As for the app ... it will set you back $1.99.

Kim's teaching her little sister a lesson or 2 in apps.
