Software Studio
We build things people actually enjoy
Apps, websites, and creative tools — designed with care, built with purpose.
What We Do
Mobile Apps
Beautiful, fast apps for iOS and Android that people love to use every day.
Websites
Clean, modern sites that look great on every screen and load in a flash.
Creative Tools
Fun, useful products that solve real problems and spark a little joy.
We don't build everything.
Just the things that matter.
CoreUp is an independent software studio. We care about clean design, reliable code, and thoughtful experiences. Every project we take on is something we'd want to use ourselves.
How We Work
01
Simple by default
We strip away the noise and focus on what actually matters to the user.
02
Crafted with care
Every detail is intentional — from the first tap to the last pixel.
03
Built to last
No shortcuts. We write clean, maintainable code that stands the test of time.
