Share Selector is a free Android app developed by midori no kaze that facilitates the sharing of content between different apps on your device. The app was designed for users who have experienced issues with their devices remembering the "always" option for certain apps when sharing content.

Share Selector is a shared app that cannot be launched from the apps menu. Instead, it functions as a "Share(Intent)" force throw with other apps. This means that if you make Share Selector "always", you will be able to select further "share" destinations every time, making it a convenient tool for sharing content across multiple apps. However, it is not suitable for those who want to use the same app "always".

Overall, Share Selector is a useful utility tool for Android users who frequently share content across different apps. Its simple and straightforward design makes it easy to use, and its ability to remember share destinations without the "always" option is a welcome feature.
