I get your point, but I don’t think Inter is similar enough to Circular to be a replacement for it. Inter is more of a San Francisco replacement in my book (which is how I use it on one of my websites—SF for Apple devices and Inter as a fallback). They’re both pretty, but Spotify’s UI looks very different than a UI set in Inter.
Tbh I was just reaching for a good "free font alternative" -- ofc they wont be exact clones -- but captures that "clean sans-serif design spirit" that seems to be all the rage at the moment.
