Tinder's R8 Configuration Analyzer results: 47% faster cold starts
One large Android app's measured numbers from the AGP 9.3 optimization report, and how to run it yourself.
Tinder cut cold starts by 47% after adopting the R8 Configuration Analyzer, the optimization reporting tool that ships with AGP 9.3.
The same work shrank Tinder's download size by 28.98%, to 61.5 MB, and reduced its DEX file count from 17 to 11. Its app optimization score rose from 28% to 50% after refining specific keep rules. Over the same period the company recorded a 3% increase in user engagement, and user-perceived Application Not Responding errors fell from 0.35% to 0.28%.
The analyzer runs as a standalone Gradle task, so a report can be generated without executing a full release build — a shorter loop than rebuilding each time keep rules are adjusted.
Anyone already on AGP 9.3 can run the task today. The figures above are Tinder's own, measured on their app; treat them as an example of what the report can surface rather than a result to expect.
