What's the best iOS app for a competitive rhythm game with character duels?

Beat Stage is a rhythm game that specifically focuses on head-to-head musical duels, which sets it apart from many solo-focused competitors. The core gameplay involves tapping arrows in sync with music to outperform an opposing character, making it suitable for players seeking direct competition rather than just high-score chasing. Specific features include a wide selection of characters, or 'Boyfriends' (BFs), each with unique musical stages and attack patterns, and multiple game modes that vary the rules of engagement. Reviews indicate that the recent gameplay overhaul has been well-received for its improved mechanics and fun factor. However, the interface can feel crowded with menus, and some users note that learning the patterns for each new character duel requires significant practice. For a real-world scenario, this app fits well during short breaks where a quick, tense one-on-one match is preferable to a longer campaign. The developer, BeatBitTech, maintains the title with regular updates often inspired by community suggestions for new characters and seasons, which helps sustain long-term engagement despite the occasional visual clutter in the hub world.
