App Info: Package & APK Backup

See every tracker, library, and permission inside every app on your phone. Find package names, back up APKs, check SDK versions, no root needed.

KILLER FEATURES

Tracker detection: powered by the open Exodus Privacy database, scan every app on your phone for known advertising, analytics, and tracking SDKs. See exactly which apps embed Facebook Login, Google Analytics, AppsFlyer, Mixpanel, and 25+ other trackers, in one tap, with the scan running on-device.

Privacy score: every app gets a 0-100 score based on the number and severity of trackers it embeds, so you can compare apps at a glance and see which ones carry the fewest trackers.

Native library breakdown: see every .so library inside any app, grouped by CPU architecture (ARM 64-bit, 32-bit, x86). Spot apps that lack 64-bit support and identify the underlying framework (Flutter, React Native, Unity, Hermes, OpenCV, TensorFlow Lite).

APP INFO ESSENTIALS

Find package name in one tap: search any installed app and copy its package ID instantly, useful for developers, ADB users, and anyone reporting a bug.

Check SDK version and minimum SDK: see exactly which Android API each app targets, when it was last updated, and whether it is compatible with your device.

Back up APKs without root: extract any installed app's APK file to your device storage with a single tap. Save your favourite apps before reinstalling or upgrading, or share an APK directly with another device.

View SHA-1 and SHA-256 signing certificates: verify the integrity of an installed app, compare signatures across builds, or spot side-loaded apps.

Install source detection: know whether each app came from Play Store, Galaxy Store, ADB sideload, or an unknown source.

Daily streak with gamification: open the app each day and watch your streak grow, with one grace day per month so a single missed day does not reset everything.

MADE FOR
1. Android Developers: debugging compatibility issues across SDK versions, pulling package names for bug reports, or checking signing certificates across builds.
2. Power Users: anyone who wants full visibility into what is actually installed on their phone, not just an app list.
3. Privacy-Conscious Users: checking which installed apps embed the most third-party trackers before deciding what to keep.
4. Designers: extracting app icons or sharing app details without digging through system settings.
5. Anyone Backing Up Before a Reset: pull APKs for your favourite sideloaded or hard-to-find apps before a factory reset or device switch.

COMMON QUESTIONS

Where does the tracker detection data come from? From the open-source Exodus Privacy database, matched against the libraries found inside each installed app on your device.

Can I back up any app? You can extract the APK of any installed app your device permits access to; some system or DRM-protected apps may be restricted by Android itself.
