Ratings and reviews

The app improved significantly compared to what I experienced back in 2023 where it was pure greed. Now they improved it, unlocking more songs to choose from plus cheaper subscription. However, the touch detection needs fixing because my touches would be detected halfway through the bars hitting the notes next to what I am supposed to hit. Most of the time my touches would not register in long notes as well.

Hi, can we please check the game? It seems like there might be a bug with hitting the notes. I keep missing them even though I'm sure I'm pressing the correct notes at the right timing for each part of the song. Im using Nubia RedMagic 10 pro

The development for this game as of late 2025 is much more active now, with new content, events, and gradual improvements on the game. It is worth going back, especially if you were a fan of Music & Beat, O2Jam U, and O2Jam Analog. As for PC-era players, most of the original classics are playable here.
