Article Summary
Dream11's 110M+ users join fantasy sports contests minutes before deadlines. A slow app launch means lost revenue and unfilled contests.

Key Takeaways
- Automated Jenkins + Fastlane pipeline tests launch time on every build
- Firebase Performance (Android) and custom metrics (iOS) capture real data
- Historical metrics in Kibana with Slack alerts catch regressions early
- Launch time data available pre-release enables fixes without delaying timelines
- Manual review removed from release process using threshold-based automation
Critical Insight
Dream11 maintains consistent app launch times across releases by automating performance testing before code ships, protecting user experience during peak traffic.
