Project Overview

Noumi is a mobile fintech wellness app designed to help Gen Z and Millennial users better understand emotional spending and build healthier financial habits.

Unlike traditional budgeting tools that focus solely on numbers, Noumi uses AI to detect impulse purchases, forecast financial stress, and support behavior change through personalized routines and emotionally intelligent nudges.

My Role

Timeline

12 Weeks

Tools

Figma, Dovetail

Problem Statement

Most finance apps focus on tracking numbers, not behavior. They fail to address the emotional reasons behind spending, leaving users without the tools to understand patterns, avoid impulsive decisions, or build sustainable habits.

Solution

Noumi helps users:

  • Identify emotional spending patterns

  • Build weekly financial habits tied to personal goals

  • Receive real time support and feedback based on behavior

  • Forecast financial stress before it becomes a problem

Goals

  1. Help users recognize and understand their emotional spending patterns

  2. Encourage healthy money behavior through personalized, easy-to-track habits

  3. Use past spending data to provide predictive insights and timely nudges that alert users to potential financial stress, helping them stay in control

  4. Create an app experience that is intuitive, motivating, and emotionally aware

  5. Launch a functional MVP integrated with live transaction data via Plaid

Project Context

12 week MVP built with a small team of designers, engineers, PMs, and data scientists.

As one of two product designers, I led user flows, visual design, feature prioritization, and early testing. I collaborated closely with engineering to ensure technical feasibility and cohesive handoff.


Research

Using multiple research methods, I uncovered market gaps and revealed how existing products were falling short of user needs.

of U.S. adults say money negatively impacts their mental health

43%

of Americans make mostly unplanned purchases, spending an average of $281.75 per month

73%

of consumers have made impulsive purchases to cope with stress, anxiety, or depression

52%

Competitor Analysis

I analyzed a range of finance and coaching apps to understand how others approach money management, emotional support, and behavior change.

While many tools performed well in either budgeting or gamified habit tracking, few successfully combined emotional intelligence with real-time, personalized guidance. This revealed a clear opportunity to create a more holistic, human-centered experience.

Key Gaps Identified:

  • One-size-fits-all advice that lacks emotional or financial context

  • Gamification features without meaningful coaching or accountability

  • Disconnected user flows that make managing money feel overwhelming or impersonal

Interviews

We conducted a mix of in-person and virtual interviews with 25 participants between the ages of 25 and 35. Conversations focused on spending habits, emotional triggers, and experiences with existing budgeting tools.

Interview recordings were uploaded to Dovetail, where I used its AI-powered features to transcribe, summarize, and categorize responses.

From there, I created affinity maps to identify recurring patterns and emotional themes that shaped the product direction.

MVP Design Takeaways

  1. Emotional spending is real
    Stress, boredom, and burnout often drive impulse purchases. Users want timely support when they are most vulnerable.

  2. Data feels scattered
    With multiple apps and disconnected tools, users struggle to see a clear picture of their finances.

  3. Simplicity matters
    Busy users prefer automation and smart defaults over manual tracking and input-heavy tasks.

  4. Tone builds trust
    Judgmental or clinical language turns users away. They respond better to calm, supportive guidance that feels human and empathetic.


Core UX Challenges/Strategies

Designing Noumi meant going beyond clean screens and good flows. We had to think deeply about emotion, timing, and trust. Working with sensitive financial and behavioral data added another layer of responsibility. These key challenges shaped how we approached the user experience.

1. Designing with emotion in mind

This was not just a budgeting tool. We needed to help users notice patterns tied to stress or boredom. The tone had to be calm, supportive, and never judgmental.

2. Making AI feel human

Behind the scenes, we used machine learning to flag impulse spending and forecast financial stress. Our job as designers was to make those insights feel helpful and understandable. The AI needed to feel like a quiet guide, not a black box.

3. Supporting habit change

Building money habits is hard without momentum. We designed features that made small wins visible and rewarding. Things like weekly goals, visual streaks, and timely nudges helped users stay consistent.

4. Reducing mental load

Our audience often feels overwhelmed by money tools. We kept the interface clean and approachable, surfacing just the right information at the right time.


Key Features

These features made up the core experience of the MVP. Each one was shaped by user research and focused on supporting emotion-aware financial wellness.

Onboarding quiz

Goal: Personalize the experience from the beginning


Before syncing financial data, users complete a short quiz to set their top money goals such as saving budgeting or paying off debt. This allows the app to tailor habit plans and set the foundation for coaching and nudges.

  • Uses friendly simple language to make goal setting feel approachable

  • Enables instant personalization based on user intentions not just spending patterns

Financial forecast

Goal: Help users plan ahead and reduce stress


We visualized upcoming financial pressure using a stress meter and simple indicators. Nudges were triggered based on upcoming bills or potential low balance moments.

  • Clear forecast visuals

  • Behavior-aware notifications

  • Empowered users to feel more in control

Habit tracking and streaks

Goal: Help users build better money habits through small, consistent actions

Users receive personalized habits based on their spending patterns and financial goals. Completing daily habits adds to their streaks, making progress feel rewarding and visible. Weekly recaps highlight successful habits and reinforce positive behavior over time.

  • Habits tailored to real user behavior and goals

  • Streaks add motivation and a sense of momentum

  • Weekly recaps reinforce progress and celebrate consistency

  • Simple tap-to-complete interactions for ease and clarity

Impulse spending detection

Goal: Help users connect emotions to spending habits


Noumi flagged potential impulse purchases based on time, frequency, and amount. Users were gently prompted to reflect on what might have triggered the spend. These check ins helped build emotional awareness and trained the AI to deliver more personalized nudges and habit suggestions.

  • Micro check ins after emotional spend moments

  • Calm, supportive tone with no judgment

  • AI adapts over time based on user behavior and feedback

Engineering Collaboration

Strong design is built in partnership with engineering. My handoff process is structured, communicative, and optimized for efficient implementation.

How Noumi Works (Under the Hood)

Noumi’s backend processes live financial data to deliver intelligent, personalized insights. At a high level:

  • Bank transactions are pulled via Plaid and stored in a PostgreSQL database

  • Machine learning models classify emotional spending and forecast financial stress

  • Large language models (GPT-4) generate personalized habit plans and weekly summaries

  • A nudge engine delivers behavior-based push notifications through FastAPI middleware

  • All insights surface in the mobile app in real time, with coaching tailored to each user

Design Handoff

I delivered production-ready Figma files with organized layers, components, and clear documentation. Specs, copy, and edge cases were annotated directly in the file. I also recorded Loom walkthroughs to explain key interactions and supported implementation with async follow-ups and Slack check-ins.

Quality Assurance

I worked closely with front-end engineers to review staging builds and identify visual bugs, spacing issues, or missed states. I tracked feedback in QA sheets and shared quick fixes or updates to ensure a polished final product.

What I Learned: Designing UX for AI-Driven Products

Designing for a product powered by LLMs and predictive models pushed me to think differently about tone, timing, and clarity. It deepened my understanding of how AI and UX intersect and how thoughtful design can make complex systems feel simple, human, and actionable.
