Mobile App Design

Design mobile apps for startups and businesses — from user flows to polished UI

Mobile app design, from idea to interface.

I help startups and established businesses turn product ideas into clear, considered mobile experiences.With three years of freelance experience, I work from the initial brief and job stories through user flows, visual design and developer handoff.

Have an app in mind? Let’s talk.

01 / Kitchen & Furniture Retail

Bringing the showroom experience to mobile.

A mobile shopping app for a kitchen and furniture retailer with an established offline presence.The brief was to introduce an online shopping experience while bringing the retailer’s products, showrooms and editorial content together.My role: UX/UI design, from brief to developer handoff Status: Design delivered, App in development

The challenge

It was necessary to define a clear next step for a wide product range. The app needed to accommodate a diverse selection of goods, information about showrooms, and editorial content.My task was to make navigating this information intuitive and to establish a clear journey — from discovering products to completing a purchase.

The Concept

Offer customers two ways to find the right product: browsing independently using filters, or seeking assistance from an AI-powered assistant.

The solution

Customers can search manually and apply filters, or ask the AI assistant a question and receive product suggestions. The product page brings imagery, key specifications and the next shopping action into one view.The visual direction draws on the showroom’s interiors and furniture, using warm tones and large product imagery. Alongside shopping, the app introduces the retailer’s shows, design initiatives and other showrooms.

02 / Crypto Startup

A clearer view of a crypto wallet.

A mobile interface project exploring how an introductory experience and a wallet dashboard can share one visual language.The challengeMake financial information easier to scan. A wallet dashboard brings together several types of information: the total balance, account actions and individual asset statistics. The design challenge is to give each layer a clear place without overwhelming the screen.

The ideaBuild the screen around a simple hierarchy: balance first, account actions next, asset details below. Use a warm neutral palette and orange accents to connect the introductory screen with the wallet experience.

The solutionBalance shows first, details when needed.The orange panel groups the wallet balance with deposit and withdrawal controls. Below it, a compact time selector introduces a list of asset cards.Each card repeats the same structure, placing the asset name and percentage change above the supporting statistics.

03 / Goal-Setting App

Personal goals. Shared momentum.

A mobile interface exploring personal goals through shared sprints and reflection.The challengeConnect the goal with the next step. A goal-setting experience needs to explain more than what someone wants to achieve. It also needs to make participation and completion understandable.The design challenge is to connect the invitation to join a sprint with a clear space to reflect at the end.The ideaBring personal goals and shared participation into one experience, with reflection as part of completing a sprint.
Original size 3840x2160

The solutionThe welcome screen introduces the social aspect of the app. The home screen combines access to personal goals with an invitation to start a shared sprint.At completion, a dedicated reflection field gives users space to consider their experience before finishing a goal.Dark surfaces and flowing gradients give the interface an expressive character. White text and pill-shaped buttons establish the main visual accents.
