Fintech Mobile Suite
A regional bank needed to modernize their mobile banking experience. Their existing native apps were outdated, slow, and expensive to maintain with separate iOS and Android codebases. They wanted a single codebase that could deliver native performance while supporting new features like biometric authentication and real-time notifications.
What We Were Up Against
The client faced several critical challenges that required innovative solutions.
Separate iOS and Android apps meant double development and maintenance costs
App crashes occurred 2-3 times per week, frustrating users
Transaction processing took 8-12 seconds, causing user abandonment
No biometric authentication, requiring users to enter passwords repeatedly
Push notifications were unreliable, missing critical alerts
How We Solved It
We chose Flutter for cross-platform development, allowing us to maintain a single codebase while delivering native performance. We built the app with a focus on security, implementing biometric authentication, encryption, and secure API communication. We optimized the transaction flow to minimize latency and built a robust notification system.
What We Built
Built Flutter app with single codebase for iOS and Android
Implemented Face ID, Touch ID, and fingerprint authentication
Optimized API calls reducing transaction time from 12s to 2s
Built real-time notification system using Firebase Cloud Messaging
Created offline mode for viewing balances and transaction history
Integrated fraud detection system with real-time alerts
Added multi-currency support for international transactions
Measurable Outcomes
Real metrics that demonstrate the impact of our work
App crashes reduced from weekly to less than 0.1% of sessions
Transaction processing time decreased from 12 seconds to 2 seconds
User adoption increased by 180% in first 6 months
App store ratings improved from 2.8 to 4.6 stars
Development costs reduced by 40% with single codebase
