This is the latest iteration of my icon set , which have been used in numerous apps and websites I’ve worked on.
They’re made primarily for web use and are free to use (not sell). You can drop the SVG code in the top of your webpages (inspect this page to grab them just inside the body), then you can call them using the code snippet.
Alternatively, you can now install them using Bower, if that’s your flavor. Instructions are on the Github project.
I’m adding new icons all the time, so check back periodically.
