MajdataPlay is an open-source, community-driven Simai chart player for Android that lets rhythm players customize charts, note skins, sound effects, and menu backgrounds while providing focused practice tools to improve performance. The app is designed for users who want hands-on control over playback and practice without relying on commercial releases and offers a straightforward mobile experience for compatible devices.
Highly customizable assets: replace charts, note skins, sound effects, and the main menu background to match your preferences. MajdataPlay's Practice Mode lets you hold the fourth button to enable focused practice, select and loop a specific section of a chart, and adjust playback speed so you can slow down fast passages to match your learning pace. Android support and minimum requirements are clear: Android 6.0 or higher, Snapdragon 835 or above, and at least 2 GB of RAM.
The app gives players complete control over visual and audio elements for a tailored play experience, and practice tools help isolate and rehearse difficult sections efficiently. As an open-source, community-driven project, it encourages contributions and customization and is designed to be lightweight on devices that meet the stated minimum specs.
MajdataPlay requires a relatively modern chipset and minimum RAM, which may exclude older phones. Customizing assets can involve manual file replacement and a small technical learning curve. As a community project, it may not offer centralized commercial support or polished onboarding for every user.
MajdataPlay is developed and maintained by TeamMajdata as an open-source, community-driven project that encourages user contributions of charts and assets and supports community-led improvements rather than a traditional commercial release model.
