A mobile app's crash-free rate is essential for understanding user experience and preventing negative reviews. The ideal crash-free session rate varies depending on the number of users and sessions, but a general target is around 99.95% for apps rated above three stars. Crash-free rates can be misleading as they don't account for other stability issues like OOM and ANR errors. Continuous testing, crash reporting, and release management are crucial in detecting and fixing crashes before they affect users. Instabug provides a solution for mobile teams to monitor app performance and stability with user-centric monitoring.
