Beyond the Basics: Performance Monitoring and User Experience for Mobile App Growth
summary
Instabug describes concrete metrics and actions: track app launch as a time to interactive (cold ≤5s, warm ≤2s, hot ≤1.5s per Android Vitals), monitor screen render (.5s initial, 1s content, 1.5s total), measure UI jank where a frame > 16.67 milliseconds causes skips, and keep ANRs under 0.47% of sessions. Combine crash, bug, and performance signals into a single score called Appdex (0–1) for rollouts. Use baseline profiles, CDN/ compression, split large requests and automated stress tests to find and fix regressions.
