Overview

Banking that gets out of your way.

Lumen came to me with a fast-growing user base but stagnating engagement. The app worked, but it felt heavy and anxious — too many numbers, no hierarchy, no warmth. The brief was simple to say and hard to do: make people feel in control of their money in under five seconds.

I owned the end-to-end redesign — from research and information architecture through to a shipped, documented design system that the in-house team now extends on their own.

The Challenge

A trusted product that felt untrustworthy.

Usability sessions surfaced a clear pattern: people couldn't answer the one question that mattered — "Am I okay?" Balances competed with promotions, transactions blurred together, and key actions were buried two taps deep. Trust was leaking at exactly the moments it mattered most.

  • 01

    No visual hierarchy — every number shouted at the same volume.

  • 02

    Core actions (transfer, pay, freeze card) were hard to find under nested menus.

  • 03

    Inconsistent components slowed the team and confused users.

  • 04

    Onboarding dropped 38% of new users before their first transaction.

The Solution

Calm hierarchy, confident actions.

We rebuilt the home screen around a single, glanceable "safe-to-spend" number, demoted noise, and surfaced the three actions people use most. A new component library brought consistency, and a softer, warmer visual language replaced the cold corporate blues.

  • Glanceable home screen anchored on a single key number.
  • Action bar with the three most-used tasks, always one tap away.
  • A 60-component design system with tokens and documentation.
  • Re-sequenced onboarding with progressive disclosure.
