Minimalistic App suite to cover all the basic day to day tasks.

CSuite

In an era marked by the rise of low-power, touch based devices, the incorporation of Linux into such platforms has become an equally inescapable trend like Steam Deck, Raspberry Pi. While KDE, GNOME, and other desktop environment (DE) apps flourish, predominantly catering to high-performance personal devices such as laptops and desktops, a void persists in the realm of lower-end, touch-based counterparts that offer a good user interface while using less resource. Stepping into this void is the CoreApps Application suite, in short CSuite, made by CuboCore Group. Every facet of our suite has been thoughtfully engineered to address the unique demands of the lower-resource, touch based landscape.

  • All of our apps are designed to be touch-friendly, catering to devices such as the Steam Deck, Linux phones, and tablets. We are actively working on ensuring this compatibility.
  • Our apps are optimized to run on low-resource devices like Raspberry Pi, even in the absence of hardware acceleration.
  • Our apps are lightweight, with minimal dependencies, efficient RAM and CPU usage.
  • Bookmark support across all CSuite apps and system apps centralizes your important files, allowing you to access them from one unified app.
  • Our apps make effective use of vertical screen real estate, displaying essential information and prioritizing user-relevant content in the limited screen size.
  • The Recent Activities feature in the CSuite apps displays all opened apps alongside their corresponding files. Double-clicking restores the app along with the previously worked-on file.
  • We adhere to C++17 coding standards, ensuring clean and tested code in the latest release of the Qt framework.
