Show HN: KnockKnock – Circular video calls that bring you closer, faster(macOS)

hi hn, i’m ham!

i built KnockKnock! because I missed how easy and spontaneous it used to be to just "knock" on a friend’s door. it’s a native macOS app that sits quietly in your menu bar and lets you video call your friends instantly—no links to generate, no scheduling, just a genuine moment of connection.

it is completely free and exclusive to macOS.

we’re gearing up for our big Product Hunt launch next week, but I really wanted to share it with this community first to hear your thoughts.
