MockApp is a UI mockup tool built for iPhone, iPad, and Mac. It's for designers, developers, and anyone with an idea who needs to show — not just tell — how something should look and feel.

You get a rich library of components covering iOS, web, and desktop interfaces. Drag them onto the canvas, style them, and arrange your screens into clear flows. Apple Pencil is fully supported — so if you think better with a stylus in hand, MockApp gets out of the way and lets you draw. When you're ready, export straight to PDF and share with whoever needs to see it.

Everything stays on your Apple devices. No browser tab. No account required to start. No learning curve that takes a week to climb.

I've always believed that the best tools feel invisible. You pick them up, and they just work — no friction between the idea in your head and the thing on the screen. MockApp exists because I couldn't find that tool for mockups on Apple devices. So I built it.

It started as something I made for myself. Late nights, a lot of iteration, and a stubbornness about keeping it fast and focused. At some point it became something other people wanted to use — and that changed everything. Every feature in MockApp today came from a real person with a real problem.

MockApp is built and maintained by one developer, from Romania. I read every piece of feedback, and I take it seriously. If MockApp saved you an hour, or helped you land a client, or just made your morning a little better — that's exactly why I keep going.
