I wanted to share some websites I've found helpful in getting icons for WebApp Builder widgets and the loading screen. Feel free to share other sites you use.
The Noun Project is also a good source for icons. There's also a surprising number of unicode characters that make good icons; search for them at &what.
I like this flat icon maker site. You can search by category or tags and then customize the outline shape, color, fill, and size, before exporting image file:
Great resource, thanks for sharing. Their owl icon just looks like a guy with a huge beard.
Hah! Yes, it looks like a little bearded gnome face!

I use Flaticon.com too >> Free vector icons - SVG, PSD, PNG, EPS & Icon Font - Thousands of free icons
Filter by mono-color > stroke (filled) and edit the icon. Replace the colour black with white. Download the icon in 128 pixels. Use it in your WAB app.
This is how it looks like in WAB.
This site has loads of white icons that can be used. White icons - 4164 free white icons - Download white icons
All these sites have some great resources, but how does everyone handle giving credit to the icon's original author? Within a web app I obviously can't list a credit right below the icon in the header, but I'm not sure where I'd place a link to a separate credits page elsewhere.
We used the About widget and put all of the attribution in there.
