Redesigning a Voucher Payment App for a Gen-Z Gaming Audience

B2C Platform • Global user research • React • iOS & Android • Gaming audience 14–20

Sole Product Designer responsible for the end-to-end redesign of Neosurf's legacy mobile experience across Android and iOS - from global user research and user flows to prototypes, UI, developer handoff, implementation support and Design QA, including App Store assets.

* Due to the commercial nature of this platform, selected workflows, configurations, and business content were intentionally modified to protect sensitive business information.

About the Neosurf brand: a prepaid digital voucher that lets users pay online without needing a bank account or credit card. It's sold at over 150,000 physical and online points of sale worldwide, and accepted by more than 20,000 websites — mainly for gaming purchases like Steam, Epic Games and Google Play.

01 / Overview

The project in brief

Neosurf is a live voucher payment app for a young gaming audience. The existing mobile product needed a modernized visual language and simpler flows for its everyday actions - registration, vouchers, wallet, cards, money transfer and transaction history.

Scope

Home, sign-up, voucher check, send/withdraw funds, generate vouchers, settings and account.

Product

A voucher payment app for gamers aged 14–20, deployed globally.

My role

Sole Product Designer - research, user flows, prototypes, UX/UI, developer handoff and Design QA through launch.

02 / Challenge

Upgrading a live product to grow a loyal user base

The goal was to upgrade an existing product and give it a distinctive, sales-driven look that invites people in, growing a base of regular, returning users. The target audience - gamers aged 14–20, worldwide - needed to complete every payment action (redeeming a voucher, transferring money in, withdrawing to a bank account, generating a voucher from inside the app) one-handed, in seconds, with minimal cognitive load and no reliance on remembering earlier steps.

Target audience

Gamers, ages 14–20, worldwide.

Core requirement

Every action — one-handed, in seconds, no cognitive load.

Business goal

Grow a loyal user base with a distinctive, sales-driven look.

Additional context: on many gaming platforms, teens can't open a bank account, yet they still earn money and pay for services within the platform. Physical cash also exposes them to theft and fraud risk.
The solution: vouchers/coupons that can be converted into money and purchased through the app, usable virtually and at physical points of sale - a store or mini-market found via an in-app map, with an agreement in place with the platform.
The platform approves conversion across several currencies - currently USD and EUR, with room to expand as needed.

03 / Research

Global user research

I ran user research across multiple countries, focused on the target age group: habits, emotional responses, goals, frequency of use, timing patterns, and consistency of use. The findings shaped a colorful, gaming-inspired style over a traditional fintech look.

Habits & frequency

How often and how long users engage with each action.

Emotional response

Feelings around payment and sign-up flows.

Goals & motivations

Why and when users turn to the app.

Consistency of use

Return patterns and availability over time.

Alongside the user research, leading platforms in the youth gaming space - Snapchat, Discord and Twitch - were studied to shape a strategic approach that eases the sign-up process, the first step and the one users like least, and to explore options like a 'quick view' for jumping straight into different areas of the app. The goal: a friendly environment that conveys security and ease of use, together with a modern, high-quality look.

04 / Key Decisions

From user understanding to product decisions

Visual direction

A colorful, gaming-inspired style chosen directly from research, replacing a generic fintech look.

Rebuilt onboarding

Broke one long form into 8 focused steps with a progress bar, themed illustrations, and live validation.

Home screen hierarchy

Moved from five equal-weight stacked buttons to primary tiles + shortcuts + auth actions.

Trust & safety

Phone verification and password confirmation before any transfer, plus full error/success coverage.

Quick view & fast access

Following research into platforms like Snapchat, Discord and Twitch, a 'quick view' option was added for jumping straight into key areas of the app, easing the sign-up process — the first step, and the one users like least.

07 / Outcome

From redesign to delivery
