Do you enjoy winning and solving challenging problems? Whether you’re an experienced programmer or a beginner, codr is the app you need. Even if you’ve never seen programming code before.

Some time ago I was searching for programming related puzzle apps but couldn’t find anything decent. Most apps require “you” to write code, but that’s a no-go on mobile devices. So I had to come up with my own product.

The idea is to have a variety of challenging code problems/puzzles for users to solve, ranging from easy to very difficult. The beauty is that users do not necessarily need a programming background, just some motivation and grit is enough.

Codr is web-based, easy to use and works on almost any device. On mobile devices no install is needed, you can however add the link to your home screen.
