At ROSSUL, we believe mobile applications should be useful, usable and affordable. The journey to a great finished product begins before any code is written — with researched and tested UX design. All our insights are reflected in UI designed to facilitate efficient user workflows. When you choose ROSSUL, you are partnering with a vendor that brings years of experience to creating mobile apps to provide a simple, positive product UX.



Good UI makes complex processes simple. The key to success on mobile is producing an interface that is focused and powerful so the user can complete their tasks accurately and quickly. Our team brings UI expertise to tailor the custom solution for your mobile application.


When designing a mobile app in today's competitive environment, your success rests on creating an application that users want to use. Our studio has a user-centric approach to design that identifies the users’ needs, expectations and challenges in order to align their goals with your business goals.


User testing identifies how your mobile app will perform in real-world conditions and shows opportunities for improvements we can tackle early on — when making changes is easier and cheaper, rather than further down the line when development costs are expensive. Your ROI from leveraging UX and UI keeps users engaged and propels growth.


ROSSUL isn't your average vendor. When you choose ROSSUL, you are joining a design partnership — from the first step of the process of researching your users and industry, to understanding your goals and problems, to providing ongoing integration support of the final UX/UI product on your back-end.
