## What it is
KOOM is a high-performance online memory monitoring library for Android by Kuaishou, detecting Java heap, native heap, and thread leaks with low-overhead fork-based heap dumps. It produces detailed leak reports to help diagnose OOM crashes in production apps.

## Use cases
- detect memory leaks in android app
- monitor java heap leaks in production
- find native memory leaks on android
- track leaked threads in android app
- diagnose OOM crashes in mobile app
- dump java heap without freezing app

## When to choose
- your Android app suffers from OOM crashes in production
- you need low-overhead online memory monitoring
- you want to detect Java, native, or thread leaks with detailed reports

## When to avoid
- you need memory profiling for iOS or desktop platforms
- you only need offline heap analysis of an existing hprof file
- your project is not Android/Java-based
