I’ve worked with Fivecube since 2020, both in my current role and a number of different other ventures. I’ve always found their work to be high quality and turned around quickly.

Web App UI/UX Design Services for SaaS and B2B Products
Need a web app that is easy to use, simple to scale, and built around real user actions? Fivecube provides web app design services for SaaS and B2B products, helping teams create clear user flows, intuitive interfaces, and development-ready UX/UI design.
Confusing workflows frustrate users. Generic templates make your product forgettable. Cluttered screens bury the actions that actually matter, and adoption stalls before it starts. We've seen apps lose half their users inside complex onboarding alone. Our web application design services close those gaps early. We rely on market research and real user testing to engage people, save them time, and help your product stand out in a crowded category.
Memorable and on-brand
Launch a product that reflects your brand and gives users an experience they remember, without confusing or overwhelming them along the way.
Tailored to your goals
An internal productivity tool and a customer-facing SaaS platform have very different expectations. We study your context, users, and business goals first, then make design decisions that fit them.
Built to convert
Simple workflows, clear navigation, and user journeys mapped to drive activation and conversion rate. We use behavioral data to reduce cognitive load and meet the implicit expectations B2B users bring from other tools.
Effortless to use
Every task in your app should feel quick and obvious. We refine user flows over several iterations and factor in usability testing to bring down time on task, not just polish visuals.
Futureproof and scalable
You get a design that evolves with your product. Every handoff includes the documentation and design system foundations your team needs to stay consistent as you add features.
Ready for the competition
We study your direct and indirect competitors, learn from their strengths and mistakes, and define how your app earns its place. The result follows industry best practices while still feeling like yours.

Technologies we use
Build user loyalty with user-centric web app design
Few B2B users have patience for clumsy navigation or heavy workflows. Ground your app in real user research, refine it before launch, and remove friction while it still costs nothing to fix. That's how our web application design services protect both engagement and conversions.
Our expertise in action
Data-driven app design
Every choice we make when we provide web application design services is based on hard data, not guesses. We verify our assumptions with user testing before design handoff.
Industry expertise
We’ve been designing apps for SaaS, FinTech, EdTech, e-commerce, and Web3 since 2016. So, we’re well-versed in each industry’s best practices from the get-go.
Development-ready designs
Our designs aren’t just aesthetically pleasing; they’re also fully ready for implementation. If needed, we can also turn your design into a fully functioning app ourselves.
Full transparency
With Fivecube, you don’t have to guess what we are up to or how our partnership will unfold. We’ll clearly define deliverables and keep you in the loop.
Long-term thinking
We want your design to become a valuable long-term asset. That’s why we ensure it’s scalable in the long run and prepare comprehensive documentation to facilitate future changes.
Designed to succeed
Web apps don’t exist in a vacuum. So, we study your competitors, learn from their strengths and mistakes, and define how to help your app stand out.

Web app design services: frequently asked questions
Don’t find your question? Contact us, and we’ll answer it.
What is web app design, and what does it involve?
Web app design is the process of shaping an app's structure and user flows, laying out each screen, and building interfaces that are both clear and pleasant to use. Because web apps are interactive and task-oriented, the work goes deeper than a typical website: designers have to reduce cognitive load, direct attention, and simplify complex workflows.
What's the difference between a web app and a website?
A website mainly presents information, while a web app lets users do things: create, edit, and manage data inside the browser. That interactivity is why web application design services demand more research, more testing, and far more attention to workflows than a standard site.
How much does web app design cost at Fivecube?
There's no fixed price, since cost depends on the number of screens, workflow complexity, and whether you need extras like custom motion or graphic design. For the simplest products and MVPs, our web app design services typically start around $5,000. For a precise figure, contact us for a quote.
How long does it take to design a web app?
Timelines vary with scope. A focused MVP can take a few weeks, while a large, feature-heavy platform runs several months. The main drivers are app size, number of workflows, and your goals. If you're on a tight deadline, tell us and we'll adapt the plan.
Do you also develop the app, not just design it?
Yes. Every design ships development-ready, and if you'd like, our front-end, back-end, and full-stack teams can turn it into a working product, so design and build stay under one roof.
Can you redesign or refresh my existing app?
Absolutely. Our web app redesign services start with an audit of your current app to pinpoint sources of friction and recommend the right fixes. Based on that audit, we'll tell you honestly whether a lighter refresh will do or a full redesign is the better investment.
What kind of apps does Fivecube have experience with?
Over the past decade we've designed web apps across SaaS, FinTech, Web3, EdTech, and e-commerce. Recent examples include Lyber (Web3 digital asset platform), Rewards (reward platform), and HYCM (trading platforms). Ask us directly about your specific vertical.
