App Info is a free utility tool designed for Android users who want detailed insights into their installed applications and their permissions. This application replicates the functionality of the 'App info' setting found in Android M, allowing users to view permissions associated with apps without requiring any permissions itself. It features a user-friendly interface that lists all installed apps along with their names and version information, and also allows users to search for apps by name or package name.

In addition to app details, App Info offers a comprehensive overview of permissions, displaying their names, group names, and the apps that utilize them. Users can search for specific permissions and view detailed descriptions. The app also enables sharing of app or permission information via email, making it a valuable resource for developers and general users alike who wish to understand the permissions tied to their applications.
