The Challenge: Financial Insight Without the Friction
Despite a mature banking ecosystem, individuals in the UK face fragmented access to financial insights when managing multiple accounts across institutions.
The founders of Pennyworth, with decades of banking experience, recognized that traditional banks were not built for digital-first, goal-driven financial planning.
They set out to build a mobile app that would act as a digital private banker, making it easy for users to view, analyze, and improve their financial health.
The Goal: Delivering Control, Simplicity, and Security
To bring their vision to life, Pennyworth needed:
A mobile experience that aggregates financial data across institutions
Intelligent algorithms to estimate missing data and suggest insights
Robust frontend performance across both iOS and Android
End-to-end security, including user consent and encrypted transfers
The success of the product hinged on frontend excellence that made complexity invisible to the end user.
Our Transformation Strategy
Intuitive UI/UX for Confident Decision-Making
We designed and developed a clean and intuitive interface that presents key insights in digestible formats:
- Income, spending, and wealth status in visual dashboards
- Goal-setting features with real-time tracking
- Comparisons against population benchmarks in the UK
Native Apps Built for Stability and Speed
Design choices were focused on clarity and trust, ensuring users could act on the data they saw. After that we built the app:
- Using Swift for iOS and Java for Android
- Veroke built fully native apps optimized for performance and consistency.
- From statement aggregation to profile-based insights, every screen was engineered for a seamless experience.
End-to-End Security and Data Protection
Security was a foundational requirement. We implemented:
- AWS Cognito for user authentication and identity management
- Encrypted connections between app and backend services
- API integrations with open banking systems based on user consent
This gave users confidence in sharing sensitive financial data while meeting fintech compliance expectations.
