“We worked so hard on this app & we know there are some issues due to the massive downloads that the whole tech team is so working on!”

People on Twitter did report that they were having trouble finding the app.

But some are skeptical that she actually caused an App Store crash.

The KIMOJI app offers “access to 250+ exclusive emoji and sticker designs – along with an integrated QWERTY keyboard – all of which work with your favorite messaging apps: iMessage, WhatsApp, Facebook Messenger, email, and more.” Most of the emojis in the app are Kardashian-based.
