- Why Crumbs

Survey

As a result of our research, we gathered three key insights that we used to guide the project:

We conducted interviews, surveys and online research to develop our understanding of out potential customers base.

72% Aware of “round-up” investing

80% of participants Interest in auto-investing spare change

28% plan to budget less than €5/month for round-ups.

70% of these smartphone users have regular discretionary spending suitable for round-up investing

37% of users aged 45+ have also adopted investment apps, showing cross-generational appeal.

27% are comfortable allocating > €10/month toward spare-change investing.

Key insights

As a result of our research, we gathered three key insights that we used to guide the project:

1

Make small mean meaningful: Many users are not sure what a micro-deposit is. It feels like extra work I don’t understand. In order to reduce drop-off the finance terms were explained with plain language (“We’ll make two small test deposits—then confirm the amounts”)

2

Motivation is driven by rewards: Millennials are very stressed towards financial savings and how to invest with a lot of apprehension towards how to structure their savings. Users felt micro‑investments (round‑ups of a few cents) wouldn’t “move the needle” on their savings goals

3

Finanical jargon feels intimidating: Half of millennials found terms like “asset allocation” or “ETF” confusing, causing them to abandon the app before completing onboarding.

4

More Control & Flexibility: Participants were wary of fully automated savings, fearing they might overdraft if their balance dipped unexpectedly.

Primary obective

The primary objectives of the Crumbs are to organize these recommendations and make them as stress-free as possible. As illustrated in the graphic, key features currently on the market include robo-investments, spare change contributions, and regular deposits.

What are some key questions that should drive the design?
How might we connect people to the right resources
How might we engage informative conversations about the environment
How might we bridges the gap between consciousness and practical, everyday action
How might we people come to agreements
How might we strengthen people connection to their environment

Comprehensive Design Process

Information Architecture

Carefully structured to provide an intuitive user journey, balancing educational content, interactive features, and community engagement.

Wireframing and Prototyping

Early wireframes led to interactive prototypes, which were tested and iterated on. This phase was crucial for refining user flows and interface elements.

User Interface Design

Focused on creating a visually appealing and emotionally engaging experience. The design incorporated nature-inspired themes, intuitive icons, and an easy-to-navigate layout.

Accessibility and Inclusivity

Special attention was given to making the app accessible to all users, including those with disabilities. Features like screen reader compatibility, color blindness modes, and scalable text were included.

Dashboard screen

As a sole designer, I created the designs for both the mobile app and the website for Crumbs. The main product for crumbs is the mobile app, and the website that was built was mainly intended for the purpose of marketing and advertising what Crumbs, as a company, gives value to.When rolling out all the screens, careful attention was paid so that the color hierarchies were respected. White space was used generously to keep the layouts uncluttered and to balance out the vibrancy.

Post-Launch Strategy

Post-launch, we closely monitored user engagement and app performance. The app quickly gained popularity, evidenced by its download numbers and active user rates. However, our journey didn't stop at launch. We continually collected user feedback, leading to several updates that improved user experience and expanded app functionalities.

Conclusion

Insights Gained: My experience in designing for the fintech sector has underscored the importance of emotional design in fostering user trust, particularly among novice investors. Implementing subtle, thoughtful micro-interactions, such as animations of a coin dropping or celebratory confetti, can greatly enhance user engagement and promote the development of positive financial habits. Ultimately, creating a seamless user experience in financial applications is not about overwhelming users with data, but rather about delivering the right information at the right time to empower users to make informed and confident decisions.

What could be better: Prioritizing tasks is essential when working alone. Setting priorities might help you stay on schedule by preventing delays. Communication with stakeholders is necessary to get their opinions and make sure the project is moving forward.
