How India's Leading EdTech Platform Resolved App Quality for 1M Users Across Tier 2 & 3 Cities
India's largest online higher education company needed real-device testing across a fragmented mid- and low-end handset landscape — not a cloud device farm. Oprimes deployed 50 verified test users across 25 Tier 2 and Tier 3 cities and surfaced 188 critical issues in 4 quarters.
India's largest EdTech platform had 1M users — but its app underperformed on the low- and mid-end devices most common in Tier 2 and 3 cities, generating crashes, ANRs, and poor payment flows that internal testing couldn't reproduce.
Oprimes deployed 50 real-device testers across Tier 2 and 3 cities, guided by experienced test managers. Coverage spanned 50+ OEM models, multiple OS versions, and real network conditions — running 4 disciplines: functional, compatibility, performance, and usability.
188 issues surfaced across 9 releases — 35% flagged as Major or Critical. Root causes of Tier 2/3 performance degradation were identified and resolved, resulting in improved market retention and measurable growth in underserved city tiers.
Device Fragmentation Was Blocking Access for Millions in Underserved Cities
India's EdTech market reaches far beyond metro centres, but the device landscape outside those metros looks very different. While the platform had invested heavily in a smooth experience for urban users on modern handsets, learners in Tier 2 and Tier 3 cities — operating on low- and mid-end Android devices with constrained memory, older OS versions, and variable network connectivity — were encountering a fundamentally different product: an app that crashed, froze, and failed payment flows.
The challenge was compounded by the diversity of the problem. App behaviour on a 3G connection in a Tier 3 city, on a 3-year-old entry-level Android handset, cannot be adequately simulated in a controlled lab or a cloud device farm. Automated testing covered standard scenarios — it could not reproduce intermittent performance degradation under real network conditions, nor capture the qualitative frustration of a student trying to access course content on a device whose specs no longer matched the app's assumptions.
With 1M users and a product roadmap that demanded consistent, frequent releases — nine per year — the team needed a testing capability that could match the breadth of the real-world device ecosystem and deliver actionable results without slowing down the development cycle.
- 1M+ active users unable to access reliable learning experiences on their everyday devices
- Revenue and retention risk as Tier 2/3 markets represented the platform's highest-growth segment
- Brand damage and app store rating exposure each time a buggy release reached production
- Release velocity under pressure — nine releases per year meant no room for slow testing cycles
Real Users, Real Devices, Real Cities — Four Testing Disciplines in Parallel
Oprimes engaged with the platform's product and engineering teams to map the full scope of the problem — identifying which modules were most affected (payment flows, course navigation, media streaming), which OS and handset generations were generating the most field failures, and which release cycles were highest-risk.
50 test cases were designed and executed for each app module, covering non-functional inspections (interruptions, interface transitions, app speed), crash reproduction on low-memory devices, payment flow verification, and negative testing with invalid inputs to stress-test error handling.
The app was tested on 50 popular OEM handsets and tablet models under real system settings — validating UI rendering, navigation, screen resolution handling, sensor responses, and broken link detection across a comprehensive matrix of devices that real Tier 2/3 learners actually own.
Performance was measured under variable bandwidth conditions — 2G, 3G, and Wi-Fi — testing CPU utilisation, memory usage, battery draw, crash rates, and page rendering speed. Edge cases like fast-forward during video playback and background notification interruptions were tested in ways that cloud device farms cannot simulate.
A structured qualitative survey was conducted with 50 test users from the Tier 2/3 target demographic, capturing their subjective experience of course discovery, onboarding, playback, and checkout — providing insight that quantitative crash logs alone cannot surface.
Testing was structured to support the platform's release cadence — nine essential releases delivered over four quarters, with test cases iterated after each cycle to address newly introduced issues on low- and mid-end devices and expand coverage as the device matrix grew.
188 Issues. 9 Releases. Root Causes Resolved at Scale.
Functional, UI, and app performance issues surfaced across all release cycles and device types.
More than one-third of all issues discovered were rated Major or higher — preventing user actions that would have impacted revenue.
Multi-device, multi-OS, and multi-network scenarios tested — covering the real conditions of the Tier 2/3 device market.
Four quarters of multi-device compatibility coverage — consistent release support without disrupting the development schedule.
The Oprimes engagement gave India's largest EdTech platform what lab-based and automated testing could not: a ground-level picture of how its app actually behaved in the hands of Tier 2 and Tier 3 city learners on the devices those learners actually owned. Each of the 188 issues surfaced came with reproduction steps, device context, and network conditions — turning what had been intermittent field complaints into reproducible, prioritisable engineering tasks.
With the root causes of app performance and UX degradation in underserved city tiers identified and resolved, the platform was able to deliver a materially better learner experience to its fastest-growing market segment — translating directly into improved market retention and measurable growth outside the metro tier.
What This Engagement Teaches Us About Testing for Real-World Device Markets
Cloud device farms and automation test against idealised configurations — they cannot simulate the interaction of an ageing OEM handset, a degraded battery, and a 3G connection in a semi-urban environment. For apps serving India's Tier 2 and 3 markets, real-device crowd testing isn't an optional enhancement — it's the only reliable signal.
Embedding crowd testing into a quarterly release cycle — nine releases, one structured test run each — proved that real-device coverage doesn't have to compromise velocity. When testing infrastructure is designed for cadence, it becomes a release enabler rather than a gate. Define the testing rhythm before the first sprint, not after the first user complaint.
35% of the issues Oprimes surfaced were rated Major or Critical — but raw crash data alone would not have explained why Tier 2/3 users were abandoning sessions. Pairing performance testing with survey-based usability research from the actual target demographic gave the engineering team a human-readable account of what was failing and why it mattered to the learner experience.
