Does JTBC have an app?

Excuse me, I was wondering if you could provide me with some information. I've been hearing a lot about JTBC lately and I'm curious if they have a mobile application. I'm particularly interested in staying up-to-date with their content and I'm wondering if an app would make that easier. If they do have an app, could you please tell me where I can find it and what platforms it's available on? Additionally, if you have any experience using the app, I'd love to hear about your thoughts on its usability and features. Thank you for your time and assistance.
