Trennik is our own fitness app, currently in development. We handle the design and development from the first sketch through to app store release.

Why we build our own products

Building our own product means making the same decisions our clients face: which features to build, how to design the app, and when to release it. That experience helps us understand the whole product development process and our clients' needs.

What we're building

  • A straightforward app for tracking workouts
  • Product design, user experience, and development in one team
  • Built with the same standards we bring to client work

Status

Trennik is launching soon. If you would like to see the current version or discuss an app of your own, get in touch.
