CRiOS Fluo - Icon Pack is a personalization app for Android devices developed by Cris87. This app offers a collection of 3735 icons with a resolution of 2K SuperHD+ (360x360) pixels. It also includes 85 HD wallpapers with the same resolution. Each icon has been designed with extreme care for details, with blunt corners faithfully reproduced as the original. In addition, the interior and exterior contours have a carbon effect.

The app features a triple icon rendering process and automatic masking for missing icons. Users can inquire about missing icons directly through the app, with three free inquiries for each release. The app also has dynamic calendar support for App Stock and Google Calendar. Updates are guaranteed, and support and information for future projects can be found on the developer's website. It is important to note that this Icon Pack needs a compatible launcher to be applied. Pixel Launcher, Google Now Launcher, and other preinstalled launchers on devices do not support Icon Packs.
