What does Homepagr offer over the browser's native bookmarks and the ever-present bookmark bar? It's not obvious from the website, and there's not even a registration link. I figured out that the "login" input emails me a magic link, but most people wouldn't. Also, it's not responsive, so works rather poorly on mobile, and doesn't look very appealing. Despite my critique, I love the idea, but I think it needs more polish and functionality before people are willing to pay for it.
