SuperStar X 12+

 
The SuperStar X fandom platform is an app that allows you to participate in votes, watch videos, and apply for events related to your favorite K-POP artists. It is designed for iPhone and requires iOS 12.0 or later. It is free to download but offers in-app purchases for diamonds that can be used for various purposes. The app also counts your votes for the SBS INKIGAYO Live Vote and Hot Stage Vote, which are weekly shows that feature K-POP performances and rankings.

The app has a rating of 2.1 out of 5 stars based on 17 ratings on the App Store. Some users have praised the app for its content and features, while others have complained about bugs, crashes, and poor customer service. The app was last updated on March 8, 2023 with minor bug fixes.

Based on this information, I would say that the SuperStar X fandom platform is a good app for K-POP fans who want to support their idols and enjoy their videos. However, it may have some technical issues that need to be resolved. If you decide to try it out, I suggest you read the privacy policy carefully and be aware of the in-app purchases.
