Is there code review site I can scroll through on my phone?

I love scrolling Dev.to. It has replaced some other social apps on my phone because of the substantive feedback and discussion.

The blogging aspect is great but wouldn’t it be nice if there were an interface just for code reviews, where you can comment on lines of code?

This could be a good addition to Dev.to eventually.

But I’m wondering if there is a site like that already?

If not, should I build it? 🤓
