Challenges in UI Design and UX Design

What we hear from founders all the
time — and how we respond

Whether you’re launching an MVP or redesigning at scale, UI/UX challenges can slow progress fast. Here’s how we tackle the ones that hold teams back most often:

I’ve worked with other agencies before. They spent weeks doing user research, but the designs still didn’t match what I had in mind.

Our process starts with your product vision, business goals, and competitor insights — then we apply UX expertise to create a first prototype in days, not weeks. It’s built to align with your direction first, then tested with early adopters to surface real behavioural patterns and refine what matters most.

More About Our UX Audit

Our MVP looked clean, but the user flow was clunky — people dropped off halfway and we had no idea why.

We design UX using product logic and behavioural psychology — simplifying paths, reducing friction, and guiding users to key actions. After launch, we track drop-offs, test variations, and refine flows based on live feedback. Most products see a 30–40% engagement lift after our redesign.

About Our Product Redesign

The designs looked polished in Figma, but when it came time to build, everything fell apart.

We don’t throw designs over the wall. Every UI we deliver is reviewed with developers for feasibility, accessibility, and scalability. Figma files include tokens, spacing rules, and interaction specs. This reduces development rework and accelerates go-live timelines without compromising on quality

Our UX Design/UI Design Process

Built to simplify decisions, gather feedback fast, and scale cleanly into dev

As an award-winning

UI/UX services

company and trusted interface design company, we focus on structure first — and polish second — using live feedback, lean iterations, and deliverables that UI UX devevelopers can build from.

Wireframes & UX mapping

We outline every screen’s structure and decision path, aligning key flows before any visual design starts.

Low-fidelity prototypes

Clickable wireframes let us test core navigation and feature logic early — without wasting time on visuals.

Medium-fidelity prototypes

We apply layout structure and interaction patterns to simulate user experience with visual cues but minimal polish.

Visual component system

We define the UI direction and build reusable components in Figma to scale design consistently across your product.

High-fidelity prototypes

We create fully designed, clickable prototypes that simulate the live product — used for stakeholder sign-off, demos, and internal testing.

Feedback loops

We gather structured input from real users and your internal team to fine-tune flow, messaging, and usability before handoff.

Design systems

We codify typography, colours, spacing, interaction states, and layout logic into a scalable, developer-aligned design system.

Developer documentation

We deliver clear specs, redlines, tokens, and behaviour logic — everything the dev team needs to build without friction.

Frequently Asked Questions

Questions already
answered

What is UI/UX design?

UI/UX design is the practice of planning how a product works (UX) and how it looks (UI). At Phenomenon, we treat design as a system — where UX defines the flow, logic, and behaviour, and UI brings it to life through scalable components, visual hierarchy, and interface clarity. Both are tied to product goals, not just surface polish.

What is UI design and UX design — and how are they different?

UX design maps the structure — what users need to do, and how quickly they can get there. UI design builds the final layout, screens, and visuals. At Phenomenon, we don’t treat UX design vs UI design as a split — they’re handled as a single, strategic system built around product logic and business goals. Our process always starts with UX logic — decision paths, flows, wireframes — and only then moves to visual direction, modular UI kits, and design systems. That sequencing is what keeps products usable at scale.

What does a UI/UX designer do?

At Phenomenon, a UI/UX designer does more than wireframe and colour screens. They define user flows, structure decisions, and translate product logic into clean, dev-ready layouts. That means building prototypes early, aligning with business goals, stress-testing usability, and handing off real Figma systems — not static visuals — to developers.

What is UI & UX design in product development?

In actual product development, UI & UX design means planning everything from feature hierarchy to user journeys to developer-ready layouts. At Phenomenon, design happens with constraints in mind: timelines, scalability, and behaviour data. We use lightweight discovery, early feedback loops, and a design system approach to avoid bottlenecks later.

Why use UI/UX design for services instead of hiring in-house?

Hiring a full in-house team takes time. Our UI/UX design services plug in immediately — with a senior-level team, proven workflows, and dev-ready files. We’ve supported 120+ launches, including SaaS, fintech, and Web3 platforms, where velocity, user adoption, and visual clarity directly affect funding and retention.

Do you offer a

UI/UX design internship

Yes, our UI UX design internship is hands-on — interns work alongside our senior team on real client projects, learning everything from wireframing and prototyping to high-fidelity interface creation and documentation. It’s designed to build future-ready user experience designers and interface thinkers.

What’s the typical cost of UI/UX design services?

The cost depends on the scope — whether it’s an MVP, a full redesign, or ongoing team extension. We offer three engagement models tailored to project needs, timeline, and complexity. Book a consultation for a custom estimate.

Is Phenomenon a UI/UX design company or a UX consulting firm?

Both. We’re a full-service UI/UX design company offering strategy, design systems, and dev-ready files — but also operate as a UX consulting partner for teams needing deep discovery, audit, or validation support.

What’s your approach to user interface design?

As a user interface design company, we create dev-ready UIs using scalable components, design tokens, and performance-aligned visuals. Every design is backed by UX logic and ready for implementation from day one.
