Do most people just own it in their own (personal) name?
It is done both ways in the App Store. I would personally recommend forming an LLC and distributing your app that way for the following reasons:
- Forming an LLC is relatively cheap (and available in most, if not all states)
- An LLC protects you personally from any legal liability that (in an unlikely event) unfortunately arise
- It looks more professional (depending on the audience of your apps) if the seller is listed as a company rather than "John Doe"
The hurdles with being an LLC:
- The (minimal) added tax hassle with filing forms related to the LLC (YMMV in your state)
- The iPhone Developer application process seems to take longer as Apple requests proof of your business (in the case of an LLC simply your registration document from the state)
Do people form an LLC (or some other type of company) and transfer it to that?
You currently cannot transfer ownership of an app in the App Store from the original owner to another party (whether individual or company). See this blog post from FutureTap detailing their ordeal to try (ultimately unsuccessfully) do exactly this.
If your question was referring to initially signing up in the iPhone Developer Program and later transferring to a company account, that is possible (though it requires more time and hoops). See this FAQ from Apple providing further detail on that use case.
Also, does anyone know of any boilerplate-type disclaimers? I'd like to add quite a few to my application, but I'm not exactly sure where to start looking.
Without knowing the nature of the application and the message you are disclaiming, its very difficult to provide an answer to this question. With that being said, I am not aware of application which provide disclaimers upon first/each use. If you are referring to license agreements, Apple does not restrict you from displaying these in your application. However, note that you must display it in your application -- Apple will not display it at the time of purchase of your app.
