Banking Customer Android App
Secure native Android banking optimised for older devices
Login speed improved by 61%
App crashes reduced by 94%
Overview
Banking applications carry the highest bar for security, performance, and reliability of any consumer software category. Users will not tolerate crashes, slow logins, or any uncertainty about whether their transaction succeeded. We built a native Android banking application using Java to maximise device compatibility, with biometric authentication, certificate pinning, and root detection as baseline security requirements.
The Challenge
Customers needed a secure, responsive Android banking application that performed reliably on older and entry-level devices, with strict security requirements.
The Solution
Developed a native Android banking app with biometric authentication, certificate pinning, account management, fund transfers, bill payments, and push notifications — optimised for broad device compatibility.
How We Approached It
Security Architecture
Implemented certificate pinning, root detection, screenshot blocking, and biometric authentication before any feature development began.
Compatibility Testing
Tested across 40+ Android device models and API levels 23-34 to ensure consistent performance on entry-level hardware.
Transaction Engine
Built a transaction flow with optimistic UI updates, robust error handling, and idempotent API calls to prevent duplicate transactions.
Security Audit
Conducted a penetration test and OWASP Mobile Security checklist review before submitting to the Play Store.
