## What it is
An Android app that inspects libraries, native ABIs, permissions, components, and signing details of installed apps and APK files. It also offers snapshot comparison, statistics, and a browser-based WebUI for analyzing packages.

## Use cases
- see which SDKs and libraries an Android app uses
- check if an APK is 32-bit or 64-bit
- inspect permissions and signing schemes of installed apps
- compare app snapshots to see what changed after an update
- analyze split APKs and app bundles
- view statistics on ABI and Android version distribution across my device

## When to choose
- you need detailed inspection of installed Android apps or APK files on-device
- you want to identify third-party SDKs and native libraries in apps
- you track package changes over time via snapshots

## When to avoid
- you need static analysis of APKs on desktop without an Android device
- you want malware scanning or antivirus protection rather than library inspection

## Facets
- artifact type: application
- maturity: active
- function: developer-tools, analytics, security
- domain: android-tools, developer-tools, mobile-development
- platform: jvm
- tags: apk-analysis, native-libraries, abi-inspection, package-inspector, fdroid, snapshot-comparison, webui, android, mobile
