My random advice from the internet is to pick a different name, change the product to show the new name and launch. It might even be possible to launch without changing the name and then start changing the name, but I am not advising that just mentioning it as an option.

Mostly, nobody cares about the name 'chowder' unless your app is a soup or stew. It's not worth delaying launch or lawyering up over at the scale of a side project.

Good luck.
