An independent, one-person development lab

Ideas worth
building.

I build independent apps, publish enjoyable activity books, and develop games that bring people together. Explore the projects I’m sharing, follow new releases, and suggest what I should create next.

Built independently by one creator. Shared when ready.

You don't have to face it alone.

Whatever you're going through, you don't have to face it alone. If you want to talk, someone is ready to listen. If you're not ready, that's okay too—there's no pressure to find the right words. Support is available when you need it.

In the United States, the 988 Suicide & Crisis Lifeline is available 24/7.

What I'm making

Apps, books, and interactive experiences. Each has its own status—published work is clearly distinguished from projects still in development.

NEW PROJECT · FORMING THE TEAM

Kroenen Labs Game Studio

We're bringing together a small volunteer team to make an original game. The project is still taking shape, and we'd love more people to be part of it.

No experience required. Curiosity, ideas, and a willingness to learn are enough to get started.

Why I'm building RepRift

Turning everyday bodyweight training into a long-term skill journey, one release at a time.

Independent by design

One creator.
Different kinds of projects.

Kroenen Labs is my public home for projects ready to share. Work that is personal, internal, or not yet ready for release stays off the site.
