Mobile App Development Review from Peter Curtis
It’s comfortable and pretty easy to work with Cogniteq. The company offers competitive prices and a good quality of services. We’ve managed to establish solid ways of working but I believe that for our future project we will move forward in making all the processes even more comfortable for all of us.

Mobile App Development Review from Jan-Willem Luijters
The quality of their staff and their reliable honest management are impressive. Thanks to the contribution from the highly talented Cogniteq staff we implemented the Native Mobile Application on both iOS and Android platforms. On top, Cogniteq helped us increase knowledge of swift (iOS) and Kotlin (Android).

Web Development Review from Bahador Katouzian
Cogniteq team helped us with Web development, and we're completely satisfied with the result. Cogniteq is a team of professionals who were clear, responsive, and competent during our work. The team worked ahead of the schedule, we could see the progress during calls and all the feedback on the project status from the PM was clear and comprehensive. Should there be a project that we can’t cover with our internal resources, we will definitely reach out to Cogniteq for a quote again.

Anderson Collaborative Reviews & Testimonials
Wendy Watson
Owner at Summer Salt Gymnastics
5.0★
Digital Marketing Review from Wendy Watson
I highly recommend Anderson Collaborative. Trevor created a beautiful logo package for my company, Summer Salt Gymnastics. My company logo is better than I envisioned. He included horizontal and stacked versions in main colors, solid colors, and black/white for the logo package. He answered all of my messages and emails in a timely manner and put together many drafts until we reached the final product. Thank you Anderson Collaborative and Trevor for your communication, quality, and creativity.

In addition to these common services, many UI/UX design companies in the USA offer graphic design, motion design and animation, accessibility and compliance support, UX audit, and consultancy services.
What is the difference between user interface and user experience design?
A user interface design (UI design) focuses on what users see and interact with. It includes layout, typography, color, iconography, interactive components, and design systems.
On the other hand, user experience design (UX design) prioritizes how the product works for users, including user research, journey mapping, personas, problems, definition, information architecture, user flows, and usability testing and iteration.
When should you consider hiring a specialized UI/UX design company versus a full-service agency?
Consider hiring a specialized UI/UX design company in the USA if you are focusing on product usability, user flows, or interface design, such as redesigning a website user experience. These companies have deeper expertise in research methods, prototyping tools, and usability testing.
Choose a full-service agency when you need UI/UX design bundled with branding or development. Full-service companies offer convenience and continuity across disciplines, but their UX work may be handled by generalists rather than dedicated specialists.
How long do UI/UX design projects normally take?
Project timelines tend to scale with the complexity and scope of the engagement:
Smaller UX design efforts (like audits, interface refreshes, or lightweight UX engagements) are usually completed within 2 weeks to 3 months.
Standard UI/UX design projects for websites or mobile apps typically span 3 to 5 months.
Larger and more complex projects can take over 6 months.
