App Share and Backup is a free Android application developed by Jain Software Solution that allows users to extract APK files, take backups of selected or all installed apps, and share apps with others. It also enables users to restore APK files from a specified folder.

One of the most significant features of App Share and Backup is its ability to extract APK files from both installed and system apps. The app also provides an option to take backups of selected or all apps without requiring an internet connection. Users can send the installation files directly to their friends via different platforms like WhatsApp, Facebook, Google Drive, and more. Another impressive feature is the app's ability to share descriptions and permission details of each app, making it easier for users to understand what they are sharing. Additionally, users can uninstall apps and access the Google Play link for each app. The app does not require root access and is small in size, making it easy to operate.
