An application’s user interface design is more than the sum of its aesthetic decisions and branding. At its best, UI design is a tool for helping users achieve what they need in an efficient manner. It is a key part of the overall user experience — one that supports an application’s workflow and seamlessly delivers information and functionality.

Your choice of a partner when developing a web application’s interface design is critical.

ROSSUL has well-developed in-house UX and UI design capabilities that can

Increase user satisfaction

Applications that better integrate user interface and user experience are easier to interact with, less prone to error, and ultimately more likely to generate satisfied users.

Reduce development costs

Up to 15% of all projects are abandoned at some stage in the development lifecycle. ROSSUL’s comprehensive web application user interface design services streamline the development process and ensure all aspects work together to support the success of your project.

Deliver a strong ROI

Comprehensive web application interface design services deliver a better finished product in a more efficient, cost-effective manner. This leads to a stronger return on your investment and more value for your development dollar.


By focusing on the end user first, the team at ROSSUL has adapted our approach to meet the needs of a diverse range of clients. We’re a trusted web application user interface and user experience design company for B2B solutions in healthcare, education, IT and many other industries. Most importantly, we work closely with you to identify key performance indicators at all stages of the process, from wireframe and information architecture development to UI design, front-end coding and ongoing integration support.


Our approach to UX design is founded on a set of core beliefs about what a mobile or web application should be, and how UX design can make it happen. We specialize in web application interface designs that are useful, usable, desirable and affordable. In everything we do, we strive to turn insightful research into solutions for the problems, information gaps and workflow inefficiencies that cost you money.

ROSSUL is a UI/UX agency that commits to user-centric web application interface design to create real-world results. We’re proud to serve businesses and other organizations of all sizes, both in North America and around the world.

Our commitment to developing the best web applications begins well before a single line of code is written. From the start, we’re focused more on being a partner to the long-term success of your business than on delivering a single project. That means we strive to integrate your goals and priorities at the conceptual level, and engage in extensive preliminary research to identify opportunities and develop a more realistic picture of your users’ expectations. Investing in a properly structured UX process at the development stage helps identify the factors that can lead to project failure, and also reduces the likelihood of rework and refinements being necessary down the line. Planning, testing and an overall commitment to creating a product that addresses its users’ real needs leads to greater profitability over time and a clearer path to growing your business.
