TRMNL Blue is a theme that applies new icons to the most popular apps through a launcher of your choice. Each icon was hand-crafted with minimalism in mind. The 5,300+ Blue icons and wallpapers are inspired by old monitors with scanlines and icons are xxxhdpi which means they're HD or high enough resolution to get cool looking lined icons on any device out there.
QUICK TIPS You can manually change an icon in some launchers by long-pressing the icon you'd like to edit.
Widgets: If your widget stops, check your system settings or your battery settings to make sure the app is exempt from battery optimization. More info at https://dontkillmyapp.com/
DISCLAIMER You may need a 3rd party launcher to apply the icon pack. Please download a launcher (Nova, Evie, Microsoft, etc.) before installing.
