Bob Polacek – Appetite UI Founder
About the Creator

Hey, I’m Bob — the guy behind Appetite UI

I’ve designed everything from early-stage MVPs to full-scale mobile apps used by millions. I help build apps and brand identities for fast-growing startups. No fluff, just design that works in the real world.
Appetite UI is my way of sharing years of real project chaos – cleaned up, componentized and systemized.
I’m not trying to impress you. I’m trying to help you design faster, better, and maybe even enjoy it.
