The Challenge

Home loan customers were calling branches for things a phone should handle: EMI schedules, statements, payment confirmations, document uploads. Every call cost the company staff time and cost the customer a working-hour visit. The company needed a customer app that a first-time smartphone user in a tier-2 city could trust with money.

What We Built

A customer app that sits directly on the lender's core systems. Customers log in with their loan account, see their outstanding balance and next EMI, download statements, pay online, upload KYC documents and raise service requests without visiting a branch. Two things shaped every decision. First, the audience: many users were on entry-level Android phones with patchy networks, so screens load in stages, payments retry safely and nothing depends on a fast connection. Second, the regulator: every data flow was mapped, sessions time out, and sensitive fields never touch device storage.

What It Does

  • Self-service loan account access, EMI schedule & balance views
  • Instant statement downloads and secure online payment gateway
  • Digital KYC document uploads and service request ticketing
  • Offline-resilient multi-stage loading tailored for entry-level devices
  • Bank-grade regulatory compliance with auto session timeouts & PII security

How We Worked

Weekly demos to the product and compliance teams from week two. Release trains every two weeks. A staging build that mirrored production data shapes so compliance could test real journeys before sign-off.

Stack

Flutter, Android Native, REST APIs, Firebase, Core Lending Engine

Results

  • 50,000+ installs on Google Play
  • Stable release history with no crash spikes after updates
  • Branch call volume for statements and EMI queries reduced (exact figures held by the client)
  • The same team still ships releases and handles store compliance today

What This Shows

A fintech app is judged on the boring parts: it opens, it is correct, it does not lose a payment. That is what we optimise for.
