UX/UI Design

An interface that stops losing users in onboarding and at checkout. Design isn't a separate contractor here: the people who draw the screens also write the code. UX audit from $2,500, app design from $6,900; a UX review of one user flow and a screen prototype are free, in 5 days, before any contract

When it matters

Situations where we help

If you recognize even one, we can be useful

01

1,000 sign-ups, and 85% never take a single action

A 7-step onboarding, confusing terms, no hints. Whatever your CAC is, 85% of that acquisition budget goes down the drain every month. Cutting onboarding to 3 steps brings back 20–60% of users.

02

Pricey mockups from a design studio: 0.8% conversion instead of 2.5%

Design without UX research is expensive guesswork. The "Add to cart" button is hard to spot, checkout spans 6 screens, there are no trust signals. With 50K visitors a month, that gap costs you 850 orders every month.

03

Every page built from scratch, no design system

Without a design system, development slows down 2–3× with every new module. Fixing one button takes a day. Visual chaos builds up and erodes user trust.

04

An MVP without a designer, and investors don't buy it

Overloaded screens, unintuitive navigation, a mobile version that's just a shrunken desktop. Trial-to-paid conversion is 2–3× below the market. First impressions form in 50 ms.

What you get

Features and benefits

Concrete results we deliver for you

01

UX research with Hotjar and GA4

In-depth interviews, Hotjar and GA4 analysis, Jobs To Be Done. We know what gets in your users' way before we draw the first screen. Every decision is backed by facts.

02

A Figma prototype with usability tests

An interactive Figma prototype plus usability testing with 5–8 users. A mistake in the prototype takes hours to fix; the same mistake after development costs weeks and dozens of times more.

03

Mockups don't die at the handoff to development

The people who design are the same people who write the code later, so Figma never holds screens that "can't be built". Loading states, errors and empty screens get agreed on once, not in back-and-forth between two contractors.

04

A design system makes UI work 2–3× faster

A library of reusable components in Figma + Storybook. Brand consistency is maintained automatically, and developers assemble screens from ready-made blocks.

05

A UX audit with an ROI forecast for each fix

Heuristic evaluation against Nielsen's 10 principles, CJM analysis, analytics data. The output: a prioritized problem map and a forecast of how each improvement will affect conversion.

06

Mobile-first for 70% of traffic

We design for mobile first, then scale up to desktop. Every element is optimized for touch. The result: equally high conversion on every device.

Process

How we work

A transparent process with clear stages and deliverables

1
Stage 1

UX review of one user flow: 5 days, free

After a 30-minute call, we review the flow where you're losing people: onboarding, a form or checkout. You get a prioritized problem map and a clickable prototype of that screen, before any contract or prepayment.

2
Stage 2

UX research: 3–5 days

User interviews, an analytics review (GA4, Hotjar, Amplitude), competitor benchmarking. We build personas, a CJM and a map of barriers.

3
Stage 3

Architecture and wireframes: 3–5 days

Structure, user flows, wireframes of the key screens. We agree on the visual direction on 2–3 screens before drawing the rest: that's the cheap point to change course.

4
Stage 4

UI design and prototype: 2–3 weeks

Visual style, design system, every screen. An interactive prototype for usability testing.

5
Stage 5

Testing and handoff: 3–5 days

Usability tests with 5–8 users, iterations. Handoff: the design system, specs, Figma Dev Mode.

6
Stage 6

Support during development

We answer developers' questions, work out edge cases and check the build against the mockups.

Cost
from $2,500
What's included
  • Start free: a UX review of one user flow and a clickable prototype of that screen in 5 days. You keep the prioritized problem map, before any contract
  • Product UX audit: from $2,500, 1–2 weeks. Nielsen heuristics, CJM, Hotjar and GA4 analysis, a prioritized list of fixes. Your own team can implement it
  • Mobile app design: from $6,900, 3–4 weeks. Research, a prototype with usability tests, every screen, handoff via Figma Dev Mode
  • Web platform or account area design: from $8,900, 4–6 weeks. A design system with components and documentation: from $6,900, 2–3 weeks
  • Two rounds of revisions per stage are included. Figma files live in your organization from the start, with full rights. No handoff markup when design comes with development

The final cost depends on scope. We'll work it out after a short call.

Prices shown are indicative and for information only; they are not a binding offer. The final cost is set in the contract once the project requirements are agreed.

Design that sells, not just design that looks nice

We start for free: in 5 days we review one user flow where you're losing people and send you a prioritized problem map and a clickable prototype of that screen, before any contract or prepayment, and the review stays with you. Then comes a product UX audit from $2,500 in 1–2 weeks, mobile app design from $6,900 in 3–4 weeks, web platform design from $8,900 in 4–6 weeks, and a design system from $6,900. The price ranges for every service are on the pricing page.

The difference from a design studio is simple: with us, the mockup doesn't die at the handoff. The people who design are the same people who write the code later, so Figma never holds screens that "can't be built". The proof: the Dubler SaaS, 29 screens with skeletons, live progress cards and asynchronous UX; Alluno, a platform for design studios where approving a mockup takes one click and web, iOS and Android run on one backend; a payments MVP that made it to demo day, after which the startup closed its seed round.

Design most often comes together with mobile development, a web app or a startup MVP, which is faster and cheaper than stitching two contractors together. For online stores there's a separate breakdown, UX/UI for e-commerce, covering the catalog, the product page and checkout.

Where we're not the right fit. If you need a single landing page on a tight budget, use a template or a freelancer, and we'll tell you so. If you only need a report and your own team will implement it, take the UX audit and leave with the problem map. If the problem isn't the interface but what the product does, start with CTO as a Service. To estimate the order of your budget yourself, use the cost calculator.
