Mobile Banking Application
Secure, feature-rich mobile banking application serving 500K+ users with advanced security features and intuitive user experience.
Project Background & Objectives
Regional Banking Institution was losing 2,400 digital-native customers per month to neobanks, solely because their existing mobile app — built in 2018 — lacked features their customers expected as standard: biometric login, instant fund transfers, expense categorisation, and real-time push notifications. Internal surveys showed 71% of customers aged 18–35 had a neobank account alongside their Regional Banking Institution account, using the latter only for salary credit. Dristi Technologies designed and delivered a bank-grade mobile application that reversed this attrition and became Regional Banking Institution's primary acquisition channel within 9 months of launch.
Customers judge the security of a bank by the speed and intelligence of its app. Counterintuitively, adding biometrics, AI-driven fraud alerts, and instant notifications actually increased perceived trustworthiness more than traditional security education campaigns.
What Problem Were We Solving?
Regional Banking Institution's legacy mobile app scored 2.1/5 on both iOS App Store and Google Play. It lacked biometric authentication, requiring customers to enter a 12-digit customer ID and password each login. International transfers required visiting a branch. The app crashed on Android 13 and iOS 16 due to SDK deprecations the internal team lacked capacity to address. Meanwhile, RBI's digital banking guidelines mandated specific security controls — including end-to-end encryption of all transaction data and customer-level audit logs — that the existing app did not satisfy.
How We Delivered Results
We built a React Native application with a shared 85% codebase across iOS and Android, cutting ongoing maintenance costs significantly. Biometric authentication (Face ID and fingerprint) was implemented using the device's secure enclave — credentials never leave the device. An AI-driven spending insights engine categorises transactions in real time using a fine-tuned NLP model. Real-time push notifications for every transaction are delivered via Firebase with sub-2-second latency. Bank-grade encryption (AES-256) covers all data at rest and in transit, and the app passed a third-party penetration test with zero critical findings.
Conducted 60 user interviews across 3 customer segments, benchmarked 12 neobanks, and ran a UX audit of the existing app to produce a prioritised feature roadmap.
Designed the security model with Regional Banking Institution's CISO team, documented RBI compliance mapping for all 23 regulatory controls, and engaged a third-party pen tester from day one.
Built the shared codebase with modular feature flags for bank-specific customisation, integrated 7 existing banking APIs, and established an automated regression test suite with 94% coverage.
Ran a 3,500-user closed beta for 8 weeks, addressed 94 UX issues and 3 security findings before wide release, achieving a 4.7/5 rating in the first week on both stores.
Built With Industry-Leading Tools
Every technology was selected for its production readiness, scalability potential, and fit with Regional Banking Institution's long-term roadmap.
In Their Own Words
“Our board asked me why it took us so long to build this app. The honest answer is that we needed the right partner, not just developers. Dristi Technologies brought product thinking, security expertise, and delivery discipline together. The result speaks for itself — our mobile channel is now our best branch.”
