Just to support anyone who still want the old APP-BITS icon pack, I've kept this around!
Icons come in standard 26px and Retina 52px sized PNGs.
Use them for commercial or personal projects, just don't alter or resell them.
Get early releases of new icon sets in the newsletter. I know you are busy so posts are useful and infrequent. I will NEVER sell, rent or share your email address.
