I'd suggest running this by the Git project, considering they applied for a received a trademark specifically to crack down on use of the Git brand like this, and wrote up a pretty detailed post earlier this year:[1]
> this is necessary to prevent dilution of the mark for other uses, but there are also cases we directly want to prevent. [...] For example, imagine a software project which is only tangentially related to Git. [...] We don't endorse it, and it's just using the name to imply association that isn't there.
Given that this has basically nothing to do with Git but is instead built around the GitHub API, the name here is a little problematic.
If it weren't the case that this is already such a problem, I'd say you missed out on the opportunity to call this "GitNotified".
