Arcticons (Arctic icons) is a line-based icon pack forked from Frost but rebuild with consistent sizing and adjustments specifically for lines in mind. Arcticons is FOSS and provides mostly icons for open-source apps on F-Droid (but there are many other apps in this pack too). The design is simple and clean with minimal lines that give you a nice see-trough effect.
Arcticons includes support for a lot of lauchers like Trebuchet, KISS, Nova, Apex, Holo, ZenUI, ADW, and many more. The installation depends on your launcher, it's probably somewhere in the settings. There are over 1700 icons.
Submitting icon requests helps a lot, but maintaining the project (as you may imagine) takes a lot of time and effort, so please be patient about adding new icons. Contributions for new icons are always welcome, and no experience with programming is necessary.
Disclaimer: You can always submit a request, but that doesn't guarantee that it actually will be made. Creating icons can cost a lot of time.
This app doesn't have an icon request feature, so you'll have to do the following steps.
- Install Turtl which can extract the icons and class names of your apps.
- Grant the storage access permission to Turtl in your system settings, this will allow it to save the zip file (Only required in Android 6 "Marshmallow" or newer, older versions grant this permission on installation).
- Open Turtl and follow the process to save the new zip file to your phone.
- Make an issue titled "Icon Request" and attach the zip file.
