In the fast-moving world of fintech, user trust is everything. One security glitch or a broken payment flow can mean not just lost customers, but lost credibility.
So when a growing fintech startup came to us overwhelmed by bug reports and negative reviews, we knew exactly what to do. Within weeks, we helped them cut user-reported bugs by over 80% — and dramatically improve their app rating.
Here’s how we did it — and how we can help you do the same. 👇
🏦 The Client: A Rapidly Growing Fintech App
The client is a mobile-first startup offering digital wallets, peer-to-peer payments, and bill splitting. With an expanding user base, their team was under pressure to deliver fast — but the bugs were piling up.
Key Issues They Faced:
- 200+ monthly bug reports
- App crashes during peak hours
- Compatibility issues on Android mid-range devices
- Delayed release cycles due to poor QA process
- 3.2 App Store rating driven by negative feedback
They needed a QA partner who could stabilize the product without slowing down growth.
🧪 Our Approach: A Custom QA Overhaul
We started with a full QA audit to understand their current pain points, then built a tailored strategy covering the full testing lifecycle.
🛠 Step 1: QA Strategy & Test Coverage Expansion
- Created a QA roadmap aligned with product release goals
- Expanded test coverage across iOS and Android (12+ real devices)
- Identified critical user journeys prone to failure
- Introduced functional, regression, and performance testing
⚙️ Step 2: Automation Framework Rollout
- Deployed Appium-based test automation for high-volume flows (sign-up, payments, transactions)
- Integrated automated tests with their CI/CD pipeline (GitHub Actions)
- Set up nightly test runs to catch issues before daily standups
🧠 Step 3: Bug Prioritization & Fast Feedback Loops
- Streamlined bug triage using Jira + TestRail
- Defined a severity-based bug escalation model
- Integrated testing insights into agile sprints with real-time dev collaboration
📱 Step 4: Real Device Lab Testing
- Simulated real-world network conditions (3G, 4G, offline)
- Performed compatibility testing on 20+ Android and iOS versions
- Included biometric login, camera-based KYC, and payment gateway validation
📊 The Results: From Friction to Flow
Within 6 weeks of launching the new QA process, the difference was dramatic.
| Metric | Before | After (6 Weeks) |
|---|---|---|
| Monthly Bug Reports | 230+ | ↓ 45 |
| App Crash Rate | 3.9% | ↓ 0.8% |
| Average Release Time | 18 days | ↓ 9 days |
| App Store Rating | 3.2 | ↑ 4.5 |
✅ Bug reports dropped by over 80%
✅ User trust and retention improved significantly
✅ Team released faster, with fewer rollbacks
🎯 Why It Worked
- Focused on critical user journeys that impacted trust
- Balanced manual and automated testing for speed & accuracy
- Embedded QA into the development cycle, not afterthoughts
Simulated real-world use — not just lab conditions.
