Products

Software we build and run ourselves.

Our own products force us to make the same decisions as our clients: what do users really need, what can it cost, how does it stay maintainable? That experience goes into every client project.

Better Window Switcher

macOS 14 or later · native Swift

Features

  • Seven layouts, from Cover Arc and Carousel to Flip 3D
  • Tabs from Chrome, Safari, Firefox, Brave, Edge, Vivaldi and Opera
  • Search across every window and tab
  • Includes minimized windows, full-screen apps and other Spaces

Krace

Android · native Kotlin

Launching 2026

Know the road. Feel the drive.

Krace reads the road ahead and calls every corner out loud in rally style, timed to the speed you are actually driving. Plan routes in the app or import them from GPX files and Google Maps, then drive them offline on GPS alone.

Features

  • Callouts that continuously retime to your speed
  • Route preview with callout simulation
  • Free Roam: automatic callouts without a planned route
  • Plan online, drive offline
