Small apps for a brighter everyday.
Kroess Labs makes calm, private apps that do one thing well, so you spend less time on your phone and more time on your life.
Three apps, one idea: real life first.
Each app is small on purpose. No feeds, no noise, no account you don’t need.

Two more apps are taking shape in the lab. Their names are still a secret, even to us.
Made to be put down.
Good apps fit into your day and then get out of the way. These are the rules we build by.
Private by design
No tracking and no selling of data. What you do in our apps stays on your device, or goes only where you send it.
Small and focused
Each app does one job and does it well. No endless feeds, no features for the sake of features.
Real life first
Our apps ask for a minute, not an evening. The best part happens away from the screen.
Crafted with care
Designed and built in Freiburg, with attention to every detail, from the first tap to the last reminder.
A small studio at the edge of the Black Forest.
Kroess Labs is an independent app studio based in Freiburg im Breisgau, Germany. We design, build and look after every app ourselves, for Android and iPhone.
We make the kind of apps we want on our own phones: useful, beautiful and respectful of your time and your data.
