The Problem
FinFlow needed to launch on both iOS and Android quickly with a small internal team, while meeting strict security and compliance requirements for a financial product. Maintaining two native codebases wasn't feasible for their timeline or budget.
The Solution
We built FinFlow's app in Flutter with a shared business logic layer, biometric authentication, and end-to-end encrypted data sync. A rigorous QA process, including penetration testing, ensured the app met financial-grade security standards before launch.
“SwiftAppStudio's engineering rigor gave our board the confidence to move forward with a single-codebase strategy. It's held up at scale.”
