Overview

Arcis is a personal finance app built for 25–38 year olds navigating financial complexity for the first time — student debt, investment accounts, tax planning, and daily budgeting in one place. The product concept was validated and the prototype had been through three rounds of investor review. What it lacked was an experience that felt worthy of the trust it was asking users to give it. We were brought in at the pre-launch stage to design the full product UI/UX from validated flows to a shippable developer-ready system.

Challenge

Financial apps exist on a trust curve — every moment of confusion is a moment of doubt. The existing wireframes revealed several structural issues: account aggregation felt abstract and hard to verify, spending insights were buried behind three taps, and the onboarding flow was 14 screens long with no perceived progress. The visual direction inherited from early prototypes used generic fintech conventions — dark blues, thin white type, and shield iconography — that blended into a category already crowded with identical aesthetics.

A person with closed eyes is covered in shimmering, iridescent glitter, creating a surreal and ethereal appearance against a soft, blurred background.

A person in a flowing white dress is captured mid-motion with hair flying back, enveloped in ethereal lights and digital glitch effects against a neutral background, conveying a sense of dynamic energy and surrealism.

Solution

We restructured the app around a financial picture mental model — a home screen communicating net position, recent movement, and upcoming commitments at a glance. Onboarding was rebuilt as a 5-screen adaptive flow with smart defaults and contextual explanations that reduced time-to-value. The visual language broke from fintech convention intentionally: warm neutrals, expressive data visualisation using custom charting components, and a type system that felt human rather than institutional. Usability testing across 22 participants yielded a System Usability Scale score of 87.

In Numbers

A product design engagement that gave Arcis the interface their financial product deserved — one where clarity and warmth replaced the cold conventions of a category overdue for reinvention.
