Useful everyday tools,
play that stays with you.
Hello, I'm Hyeonwoo Kim.
I make apps that fit into everyday life and games you can enjoy at your own pace.
Ideas into screens, screens into everyday life.
A FEW THINGS I'VE MADE
Here's what I'm making.
Apps and games that began with a small idea.
Make everyday life a little easier.
Tools to organize, record, and make your own.
Follow your curiosity.
Play through puzzles, drawing, and stories.
BEHIND THE WORK
Even small ideas
are worth seeing through.
I like useful tools and am curious about new ways to play. I plan, design, and develop apps I'd want to use and games I'd want to keep exploring.
I bring ideas to life with Flutter and Unity, refining the experience from a single tap to the flow between screens. This is where I collect the projects made along the way.
