A clean, transparent, and private Android utility to inspect installed applications, analyze storage breakdown, check permissions, track screen time, and safely export APKs offline.
Modern smartphones carry hundreds of preinstalled system components, background services, and user applications. Understanding which apps take up storage space, what permissions they have been granted, and how often they are actively used is essential for device health and digital privacy.
App Manager was engineered to provide total transparency without demanding root permissions, scraping settings screens, or running background battery-draining monitors. Using official Android APIs, App Manager compiles a rich, structured inventory of all software on your device, complete with package architecture (Single APK vs Split APKs), installation sources, signing certificates, and granular storage measurements.
Complement your device toolkit by combining App Manager with Phone Toolbox for hardware diagnostics, Voice Mate for private offline voice memos, and DocsStudio for local document editing.
Features and Why They Matter
Comprehensive App Inventory. Browse all installed applications with instant categorization into User apps and System packages. View version names, internal version codes, install dates, and update timestamps at a glance.
Granular Storage Diagnostics. Inspect accurate byte-level measurements of APK size, app data, cache footprint, and total storage consumption using Android's native storage statistics.
Security & Permissions Auditing. Review every requested and granted permission for any application, highlighting sensitive capabilities such as location, camera, microphone, and contacts.
Usage Access & Unused Apps Detection. Leverage Android's UsageStatsManager to track real screen time across custom timeframes (daily, weekly, monthly) and pinpoint inactive applications cluttering device storage.
Smart Groups & Deep Filtering. Categorize large collections automatically into Communication, Social, Media, Productivity, Finance, Games, and Tools with instant sorting by name, storage size, or update date.
Safe Offline APK Sharing. Inspect signing certificates, package SHA-256 fingerprints, and install sources, then share base APK packages safely via Android's secure sandboxed FileProvider.
Who Should Use It
App Manager is crafted for anyone who demands clarity, control, and privacy from their Android device:
Power Users & Tech Enthusiasts: Inspect package internals, identify split APK configurations, check signing certificate digests, and audit background permissions.
Storage Management & Device Hygiene: Quickly discover heavyweight apps, inspect cache and data ratios, and identify dormant applications that haven't been opened in months.
Privacy-Conscious Individuals: Verify exactly which permissions each installed package possesses, with zero fear of personal telemetry or data leakage.
App Testers & Android Developers: Verify build version codes, target SDKs, install sources, and share test builds with peers effortlessly.
Privacy-First Data Handling
Unlike many system utilities that monetize user insights or transmit package catalogs to remote analytics databases, App Manager adheres strictly to a 100% on-device privacy guarantee:
The application has zero network tracking, analytics SDKs, or cloud synchronization. The QUERY_ALL_PACKAGES permission and optional PACKAGE_USAGE_STATS permission are queried locally in-memory to build the UI for the active user session and are never transmitted off the device.
For complete details on data handling, permissions, and security practices, please review our comprehensive App Manager Privacy Policy.
Fast, Lightweight Android Performance
App Manager is built using modern Kotlin and Flutter architecture with optimized asynchronous native channels. Package queries and storage calculations run on background dispatchers, ensuring silky-smooth 120Hz scrolling, instant filtering, and responsive search across libraries containing over 400 applications.
The user interface follows Material Design 3 guidelines with support for dynamic system colors, high-contrast dark mode, and edge-to-edge layouts spanning Android 10 through the latest Android 16.
Offline Architecture and Web Diagnostics
All core capabilities—app scanning, storage breakdown, permission inspection, usage analysis, and APK sharing—work completely offline without requiring any internet connection. App Manager also features a web diagnostic mode for exploring package metadata structures across desktop and tablet browsers.
Frequently Asked Questions
What is App Manager used for?
App Manager is an on-device utility to inspect installed applications, analyze storage breakdown, review permissions, track screen time, and safely share APK packages.
Does App Manager collect or upload my app list?
No. App Manager runs entirely locally. It contains no analytics libraries, no third-party trackers, and never sends your installed app catalog or usage data to any external server.
Why is QUERY_ALL_PACKAGES needed?
On Android 11 (API 30) and above, Android restricts package visibility. App Manager uses this permission strictly on-device to display your installed user and system apps.
Is Usage Access permission required to use the app?
No. Usage Access is entirely optional. It is only required if you wish to view screen time statistics and discover unused applications.
Can App Manager uninstall system apps?
No. Modifying or removing system applications requires root access. App Manager operates within standard Android security boundaries and opens the official Android App Info screen for disabling system apps safely.
