Apps and rapid prototyping

We make our own apps. We’ll build yours too.

We know what it takes to get one launched. Bring us an idea and you’ll have a working prototype in weeks, then a finished product.

Why a rubber duck

Programmers explain a bug out loud to a rubber duck, and the answer becomes clear. Rubber Duck Labs works the same way: clear problems, clear answers, sources you can check.
