Coming Soon: Beter Afrikaans

We're excited to announce that we've teamed up with Beter Afrikaans to develop an app in which users can easily perform the daily tests of the Beter Afrikaans website.

The app will be available soon on both iOS and Android-- that's right, it'll be cross-platform! We're vastly approaching the beta phase; the first version is expected to launch within months.


Stample has arrived!

Hooray! As of today, our app Stample is available in the Dutch Google Play Store.

The (Dutch) trailer below explains Stample in under 1 minute:


Coming Soon: Stample

It's almost time! After lots of blood, sweat, and tears (but mostly sweat), we are nearly ready to show Stample to the world.

Stample is a location-based treasure hunt in which you collect stamps by visiting interesting real-world locations, such as big cities or famous landmarks. Customize your stamps, learn more about the locations' histories, view your stamps on an interactive map, trade them with friends, obtain achievements, and try to be better than everyone else!

The app is available in Dutch and in English, but we will begin by kicking off in the Netherlands. If many players show their love and support, we may be able to go global!

Visit the Stample website for more information.

Keep your eyes peeled on either of these pages for a release date. :)

About us

We are Orange Gears, a duo of app/game developers in Utrecht, the Netherlands. We started creating games together as Computer Science students, many years ago. Today, we combine our part-time jobs with our own projects.

Our first app, Stample, was released in the Netherlands in Spring 2014.

Jeroen van Knotsenburg

Jeroen is a software developer at heart. He breathes C# for a living, although he could quickly learn to breathe anything you'd like him to. Look carefully and you may catch him gaming, mountainbiking, or geeking out over Nintendo.

Special powers: Writing clean and efficient code, figuring out new features, keeping patience for two while Wouter goes haywire.


Wouter van Toll

Wouter may look like an ordinary PhD student doing research on crowd simulation for games, but his secret hobbies include drawing, piano playing, (improvised) comedy, and geeking out over Nintendo. Wouter likes too many things a little bit too much.

Special powers: Designing layouts, writing cheerful text, correcting people's grammar, finding missing dollar characters in PHP.
