Don't hire based on pretty pictures alone. Learn to evaluate process, user empathy, and problem-solving skills when selecting a designer for your mobile app.
I've had three different clients come to me in the past year with almost identical problems. They'd hired a "UI/UX designer" from a cheap platform, got beautiful-looking screens delivered in Figma, and then six months after launch their app had a 70% drop-off during onboarding. Users were downloading the app and leaving within the first two minutes.
The screens looked stunning. The UX was broken. Those two things are not the same, and confusing them is the most expensive mistake you can make when building a mobile app.
UI vs. UX — Why This Distinction Actually Matters
UI (User Interface) is how the product looks — colors, typography, icons, layout.
UX (User Experience) is how the product works — the flow from opening the app to completing a task without friction, frustration, or confusion.
You need both. But most "UI/UX designers" are really just UI designers who add "UX" to their title. A genuine UX practitioner has done user research, drawn user journey maps, run usability tests, and analyzed funnel drop-off data.
What Separates a Great App Designer from a Mediocre One
These are the non-negotiable qualities I'd look for before signing any contract:
1. Genuine Mobile-First Thinking
Not "I'll design for desktop and scale down." Real mobile-first means the designer starts with a 375px iPhone viewport and works outward. They know that touch targets need to be at least 44×44px (Apple HIG guideline). They understand thumb zones — bottom-center is easy to reach, top-corners are a stretch.
If a designer shows you a portfolio of beautiful desktop apps and tells you they do mobile too, ask to see their actual mobile prototypes. The way they navigate complex data on a small screen tells you everything.
2. Interaction Design — The Details That Make Users Love You
Static mockups are lies. A Figma screen with a perfectly positioned button tells you nothing about what happens when that button is pressed. Does it show a loading spinner? Does it give haptic feedback on iOS? What does the error state look like?
A skilled app designer prototypes the flows, not just the screens. They'll walk you through a fully interactive Figma prototype that feels close to the real app so you can validate the experience before a single line of code is written.
3. Accessibility Is Not Optional
In Nepal's growing digital market, many first-time smartphone users have low digital literacy and often use their phones in bright sunlight. A good app designer ensures color contrast ratios meet WCAG AA standards (4.5:1 minimum), text sizes are legible without zoom, and critical actions are intuitive without requiring tutorials.
Ask your designer: "What's your process for checking accessibility?" If they look confused, walk away.
4. Developer Handoff That Actually Works
The handoff is where most design projects fall apart. Developers open a Figma file to find unlabelled layers named "Rectangle 47", inconsistent spacing, and assets that need to be manually exported in 4 different sizes.
A professional delivers organized, named Figma layers, a proper component library with variants, exported assets in SVG/WebP, and a clear annotation guide for any non-obvious interactions. This can save your development team 40-60 hours per project.
The Interview Questions That Actually Reveal Skill
Don't ask "Are you good at UX?" Ask these instead:
"Walk me through the onboarding flow of an app you designed. What was the original drop-off rate, and how did your design change it?"
Why this works: A great designer tracks metrics. If they can't answer this, they don't think about outcomes.
"Show me a prototype, not just screens. Can I click through it?"
Why this works: Static screens hide bad UX. Clickable prototypes reveal it immediately.
"How do you handle the case where a user fills a form incorrectly? Show me the error state."
Why this works: Edge cases and error states reveal mastery. Beginners only design the happy path.
"Can you explain your choice of navigation pattern — tab bar vs. hamburger menu — for this specific project?"
Why this works: Decisions should be justified by user behavior data or platform guidelines, not just aesthetics.
Red Flags to Watch For
They show you portfolio images on Instagram/Behance, but can't share editable Figma files
Every project in their portfolio uses the same color palette and layout style
They don't ask you about your users before starting design
They quote a price without asking about the number of screens or user flows
They've never done usability testing or user interviews
Their own portfolio website is broken or poorly designed on mobile
Your app is competing against apps built by teams with millions in funding and full-time designers. Good UX isn't a luxury — it's the only thing standing between your users sticking around and immediately uninstalling. Hire accordingly.
