Hey! Banco — Onboarding & Navigation Redesign

Hey! Banco is a fully digital bank for young adults in Mexico, built as a modern alternative to Banregio's legacy app. With no physical branches, the mobile app is the only place users onboard, understand the product, and build trust — and the original experience was overwhelming people before they ever got there.

My Role

I led the UX and interaction design for onboarding and the app's global navigation — owning the flows, information architecture, and usability decisions behind how the product works, and applying our visual designer's design system (color, type, iconography, component styling) across every screen shown here. I worked alongside a cross-functional team of six designers covering individual product areas (debit and credit cards, rewards, insurance), plus two stakeholders, one product owner, two financial advisors, and a development team of ten (five front-end, four back-end, and one technical lead). Working with that development team meant handing off detailed design specs, running feasibility check-ins throughout the build, and pairing interactive prototypes with QA passes on the built screens to keep what shipped true to what was designed — keeping the experience cohesive, intuitive, and technically feasible across the platform.

From chaos to clarity

Before jumping into solutions, I mapped the shift I needed to lead the team through — from a cluttered, disorienting first-time experience to one built on radical clarity.

Why users abandoned onboarding

I combined quantitative funnel data with qualitative interviews to understand both the usability issues and the emotional friction driving drop-off.

“Users were not abandoning onboarding because tasks were hard — they were abandoning it because they felt uncertain and lacked confidence. Onboarding was not failing functionally. It was failing emotionally.”

“I hope to be able to buy a house in a maximum of 10 years. I better start building my credit history now.”

Goals

  • Make the most out of her money
  • Get approved for a credit card
  • Build an investment portfolio before 30
  • Track income and spending better

Frustrations

  • Great products often carry high annual fees
  • Cannot get approved without credit history
  • Her bank's app is confusing and slow
  • Worried about getting scammed

Turning insight into a UX strategy

Using the research, I facilitated collaborative ideation sessions to explore how onboarding and navigation could be restructured — challenging assumptions and validating direction early, before committing to high-fidelity solutions.

Key focus areas

  • Reducing cognitive load during first-time use
  • Improving onboarding clarity and sense of progress
  • Simplifying navigation hierarchy across products
  • Creating predictable, easy-to-follow user flows
  • Respecting native iOS (Human Interface Guidelines) and Android (Material Design) conventions
  • Meeting accessibility standards for color contrast, tap-target sizing, and screen reader support

Activities

  • Crazy 8s to widen the solution space before committing to one direction
  • Rapid wireframes to pressure-test flow logic before any visual design
  • IA exploration to simplify the navigation hierarchy across products
  • Group critiques to catch blind spots before testing with real users
  • FigJam whiteboarding to keep the team aligned on one flow model

Solving structure before visuals

I translated the strategy into low-fidelity wireframes and flows to validate onboarding logic and navigation structure — reducing risk before any visual design work began.

Approach

  • Low-fidelity wireframes
  • Flow diagrams and interaction mapping
  • Rapid iteration and internal reviews
  • Early usability validation — no visuals yet

What this validated

  • Onboarding flow logic and progression
  • Step-based interactions that reduce cognitive load
  • A simplified navigation hierarchy across products
  • Task clarity and predictability

What real users told us

Real users tested the flows to validate clarity, effort, and confidence — focusing on onboarding clarity, navigation discoverability, task efficiency, and user confidence. Sessions ran through UserTesting.com alongside internal moderated testing to reach a broader pool of first-time users.

What improved

Faster onboarding
Users completed flows with fewer errors
Reduced uncertainty
Users stopped guessing how much was left, so they kept going instead of abandoning partway through
Better discoverability
Users found key features without hunting, so fewer gave up out of frustration before ever using the product
Higher trust
Users felt more comfortable completing tasks

What we learned — honest frictions

  • Welcome screen needed a clearer purpose
  • Stronger visibility of security and data protection
  • Mixed expectations around promotions
  • Faster access to the security token needed
  • Clearer step indicators required
  • Visibility of digital signature for legal compliance

20% higher retention. 30,000+ new accounts.

By restructuring the information architecture and clarifying key user flows, the experience became faster to complete and more reassuring — reducing drop-off and building the trust users need to commit to a new financial product.

Measured by comparing the first fully launched version, released in mid-2020, against 2019 baseline numbers.

Faster
Onboarding completion with lower abandonment
Clearer
Reduced confusion at critical decision points
Higher
Task success rate and first-time user confidence
“In fintech, designing for emotional clarity and trust is just as important as designing for usability — and it is what moves the business metrics.”

Looking back: the welcome screen stayed on my list of honest frictions longer than it should have. Users moved through the rest of the flow with far more confidence, but that first screen still did not tell them clearly enough why they were there. It is a reminder that clarity has to start before onboarding begins, not partway through it.
