What We Do...

Mobile Development & Design for iOS & Android

Our services range from developing entire applications from the ground up to augmenting existing engineering teams to help bring mobile applications to market quicker. We have prototyped early-concept applications used to help secure funding for startup businesses, and have brought full-scale applications from conception to completion. We can start with an early concept and evolve it into a complete user interface and graphics specification needed to start coding. We can also implement back-end solutions to networked applications, or connect mobile apps to existing services where appropriate.


Good design makes the world approachable. We approach design with a user-centric philosophy, making interfacing with technology not just simple and intuitive, but memorable and enjoyable as well.

Research the Competition

What is being done already? We don't want to re-invent the wheel, however we do want to be slightly ahead of the game. User behavior analysis and trends help inform how to position within the market.

Sketching it out

First the idea, then drawing a line around that idea, this way we can quickly refine it together.


Wireframes help define how the user walks through the app. This step greatly helps to see what works best before it gets the paint.


When appropriate, we will use 'live code' prototypes to demonstrate early iterations.

Usability Testing

We make sure our products are ready to hit the market before they hit the market.



We provide solid core development for native apps. Duff Lite will help provide easy solutions for companies both large and small to help make their business mobile ready.
