What's the best iOS rhythm game for competing with friends on K-Pop leaderboards?

SUPERSTAR JYPNATION is specifically designed for competitive K-Pop rhythm gamers who enjoy tracking their progress against others. The app's weekly league system automatically places users in groups of 20 players, creating direct competition where participants climb rankings by achieving higher song scores. Global leaderboards display top performers across all artists, while friend comparison features allow users to see how they stack up against their social circle. The card upgrade system adds strategic depth to competition, as higher-grade cards significantly boost scoring potential. Users report the competitive arena feature provides ongoing motivation to improve skills, though some note occasional timing detection issues during rapid note sequences. The game supports all major JYP Entertainment groups including TWICE, Stray Kids, and ITZY, with regular song updates keeping the competitive landscape fresh. While the ranking system maintains engagement, players should be aware that progression can feel gradual without in-app purchases for card upgrades.
