What We Do

Addhen specializes in developing apps for the Android platform: for phones, tablets and wearables. We are able to turn your static mockups into functional apps. We can create your app from the ground up, port it from a different platform or help maintain and improve existing Android apps.

We value direct communication, a pragmatic approach to problem solving and providing a quality consulting service.
