Mobile Banking App
A security-first cross-platform banking app with biometric login, instant transfers, spending insights, and real-time fraud monitoring.
The Challenge
Deliver a bank-grade, compliant mobile experience that customers actually enjoy using.
Our Solution
A React Native app with end-to-end encryption, biometric auth, and an analytics layer that surfaces personalised spending insights.
How we approach this kind of build
Security in a banking app is mostly about what happens around authentication rather than the login screen itself. Credentials are never stored on the device; biometric unlock releases a key held in the secure enclave or keystore, and sessions are bound to a specific device registration so a stolen token is useless elsewhere. Sensitive screens are excluded from OS screenshots and app switcher previews.
Transport is certificate-pinned to prevent interception on untrusted networks, and every state-changing request is idempotent so a dropped connection during a transfer cannot produce a double debit. That last detail matters more than it sounds — flaky mobile networks make retry logic a correctness problem, not just a UX one.
Fraud monitoring runs server-side on behavioural signals: unusual transfer amounts, new payee patterns, device changes, and velocity. The client never decides whether something is fraudulent, it only surfaces the result. Spending insights are computed from categorised transaction data, which is also where most of the perceived product value sits for everyday users.
