Quirk is made by Evan Conrad, a software engineer in the bay area.
If you need help with the app, would like to request a feature, or just want to talk, feel free to send me a line at firstname.lastname@example.org.
If you’re interested in the development of Quirk, you’re in luck! Quirk is an open source project under the GPL license. It lives on Github here.
I also announce info about it on my blog on Dev, and probably on Twitter too.
