We've been on HN a half dozen times, been featured in some trade magazines, have been a gold Mercurial sponsor, and have built-in support in competitor's products (e.g. SourceTree). We're also the second link if you google for "Kiln". I think that qualifies as relatively notable.
We also have a trademark on the name Kiln in the context of developer tools.
Edit: That last line sounds like a threat, which it absolutely isn't. Just, due to how these things work, picking another name probably makes sense.
Ooh, good point. Though one issue I've noticed popping up of late is that people are starting to associate "open source" with "GitHub" instead of with checking whether the source is open or not. So who knows, maybe a GitHub mirror of their own Kiln-hosted source for April Fool's?
Google and whois are the minimum threshold for picking names these days. If you intend to start a business, add a trademark search to that.
There's also no law against picking descriptive names.
Did you develop an egg smashing simulator? Where's the harm in calling it "Egg Smash Simulator Kit" instead of "Humpty" or some other confusing bloody puntastic name?
Developer tools for iOS, on iOS. You probably don't really care about the domain name, so there are a lot of possibilities.
Kiln is kind of a shitty name to begin with, so I'm sure you'll think of something better. I'd focus on how it's self-hosted, handheld, mobile, lightweight, and portable.
"Phone Self Exam" is one bad idea, with the obvious non-Ada Initiative approved branding concept...
