Crashlytics
A mobile application crash reporting and monitoring service provided by Google Firebase that helps developers collect, analyze and fix app crashes and ANR issues.

ANR or OOM stack traces almost never point to the actual root-cause thread or allocation site.
The Crashlytics console marks threads blocking the main thread as root-blocking, threads stuck reading large files or slow queries as IORootblocking, and threads waiting on each other as deadlocked.
GWP ASAN is a production-oriented lightweight safety net that samples a very small fraction of native allocations and wraps them in guard pages, with near-zero CPU and memory overhead, but it is probabilistic.
Crashes captured by GWP ASAN show a memory stack trace tag in the Crashlytics console, give the exact reason for the use-after-free at the top, and list the buffer's allocated by and deallocated by.
