Users loved the concept but struggled to manage their money effectively within the interface. Activation rates were strong, but long-term engagement was declining. This case study walks through the redesign process, the key decisions we made, and the measurable results that followed.
The existing app had grown organically over three years. What began as a simple spending account had accumulated investments, bill splitting, crypto trading, savings vaults, and a marketplace of financial products. Each new feature was added with the best intentions, but the cumulative effect was an interface that felt cluttered, confusing, and intimidating — especially for users who were not financially sophisticated.
Analytics told a clear story. Users opened the app an average of 4.2 times per week, but sessions were short. Only 18% of users accessed any feature beyond the home screen and basic transaction history. The savings vaults, one of the bank's most valuable retention tools, had a adoption rate of just 11%. Customer support tickets related to navigation and "where do I find X" had increased 40% year over year.
Interviews with users revealed a common emotional thread: anxiety. Many users described opening the app and feeling overwhelmed by the sheer volume of information, options, and calls to action. One user summed it up perfectly: "I open it to check my balance, and suddenly I'm being asked to invest in crypto, open a vault, and refer a friend — all before I've even seen how much money I have."
We began with a comprehensive research phase, combining quantitative analysis with qualitative insight. Our goal was not just to identify usability problems, but to understand the emotional journey of managing money in this app.
We conducted 24 in-depth user interviews, segmented by experience level: new users (under one month), casual users (one to six months), and power users (over six months). We also ran a tree-testing study with 200 participants to measure how effectively users could locate key features within the existing navigation structure.
The findings were striking. Across all segments, the number one pain point was information overload on the home screen. Users were confronted with their balance, a carousel of promotional banners, a list of recent transactions, a savings widget, an investment ticker, and a quick-actions grid — all above the fold. The eye-tracking data showed that users' gaze darted around the screen erratically, never settling on a clear focal point.
The tree-testing results were equally revealing. Only 34% of users could successfully navigate to "freeze my card" — a critical security feature. The path existed, but it was buried three levels deep under "Settings → Card Management → Security." Similarly, only 41% could find the "set up a savings goal" flow.
We also identified a significant trust issue. The app used bright, playful colors and casual language throughout, including for serious financial events like declined transactions and account security alerts. Users reported that this tonal inconsistency made them question whether the app was taking their money seriously. As one participant put it: "When my card gets declined and the app shows me a cute cartoon raccoon, I don't feel reassured — I feel like they don't understand that this is important."
Based on the research, we established three core design principles that would guide every decision in the redesign:
1. Clarity over completeness. The home screen should answer one question immediately: "How much money do I have, and can I spend it?" Everything else should be secondary, accessible but not demanding attention.
2. Progressive disclosure. Features should be revealed as the user needs them, not dumped onto every screen. A new user should see a focused, simple experience. A power user should be able to access advanced features without them cluttering the interface for everyone else.
3. Emotional appropriateness. The visual tone should match the context. Everyday interactions can be friendly and light, but serious financial moments — security alerts, declined transactions, large transfers — demand a calmer, more respectful treatment.
We also made a strategic decision about navigation. The existing app used a bottom tab bar with five items: Home, Payments, Invest, Products, and Profile. Research showed that "Products" was rarely tapped, and "Invest" was only used by 12% of users. We consolidated to a four-tab structure: Home, Payments, Savings, and Profile. Investments were moved into the Savings tab as an optional section, and the product marketplace became a discoverable feature rather than a primary destination.
The most dramatic change was the home screen. We stripped away everything except the essentials. At the top, in large, confident typography, was the total available balance. Below it, a single sentence provided context: "You can spend $2,847.50 this month after bills and savings." This sentence — dynamically calculated based on the user's scheduled bills and automated savings — was the single most impactful addition in the redesign. It transformed a raw number into meaningful, actionable information.
Below the balance, we placed a compact list of recent transactions, capped at five items with a "See all" link. Promotional banners were removed entirely from the home screen and relocated to a dedicated "Offers" section accessible from the profile. The quick-actions grid was reduced from eight icons to four: Send, Request, Pay Bill, and Add Money — the four actions that accounted for 92% of all taps in the old interface.
The result was a home screen that users could process in under two seconds. Eye-tracking retests showed a clear, linear visual path: balance, context sentence, recent transactions. No more erratic darting.
We rebuilt the information architecture from the ground up. Every feature was card-sorted by users, not by internal product teams. The resulting structure ensured that any feature in the app could be reached in a maximum of two taps from the home screen.
Critical security features — freeze card, report fraud, change PIN — were elevated to a dedicated "Card & Security" section accessible directly from the profile screen with a single tap. We also added a persistent "Help" button in the top-right corner of every screen, connecting users directly to support without forcing them to navigate through a maze of FAQ categories.
The savings vaults were completely redesigned. Instead of a generic list of vaults with balances, we introduced a goal-oriented interface. Each vault displayed a progress bar, the target amount, and an estimated completion date based on the user's current contribution rate. Small, encouraging microcopy celebrated milestones: "You're 60% there — at this rate, you'll hit your goal by March."
We also added an automated "round-up" feature that rounded every transaction to the nearest dollar and deposited the difference into a vault of the user's choice. This feature, requested by 68% of survey respondents, was previously hidden in settings. In the redesign, it was presented as a simple on/off toggle during the savings setup flow.
The visual system was refined to support emotional appropriateness. The core brand color — a vibrant teal — was retained for primary actions and positive moments. But we introduced a calmer, more muted palette for informational screens and a restrained, serious treatment for security and alert states. A declined transaction no longer displayed a cartoon character; it showed a clear, respectful explanation with actionable next steps.
Typography was simplified to a single type family with a clear hierarchy. The playful rounded font used for headings was replaced with a clean, modern grotesque that felt both friendly and trustworthy. Body text size was increased by 2px across the app, and line height was optimized for reading comfort on mobile devices.
The redesigned app was rolled out to 100% of users over a six-week period. We measured results against the previous version using a combination of in-app analytics, NPS surveys, and customer support ticket volume.
The improvements were significant across every metric we tracked:
Perhaps most telling was the qualitative feedback. Users repeatedly described the new app as "calmer," "clearer," and "like it's on my side." One long-time user wrote: "I used to open this app and feel stressed. Now I open it and feel like I understand my money. That's a huge change."
This redesign was not about adding features or chasing visual trends. It was about subtraction — removing the noise, the clutter, and the unnecessary complexity that had accumulated over years of organic growth. The most impactful design decisions were not the ones that added something new, but the ones that took something away.
The lessons from this project apply to any product facing similar growing pains. First, complexity is a tax, and it compounds with every new feature. Second, users do not want more options — they want clearer guidance. Third, emotional tone matters as much as visual polish, especially in products that handle sensitive, high-stakes information.
The bank's app now serves as a foundation that can grow without becoming overwhelming. New features can be added thoughtfully, with progressive disclosure and user testing, rather than simply bolted onto an already crowded interface. The result is an experience that users trust, understand, and — perhaps most importantly — actually enjoy using.
