This application has been on my very large todo list for a long time. Users of my Quest Games Optimizer application have asked me for an easy way to install it (as well as any apk and soon xapk) without going through the Mobile VR Station application (used to install my application) which requires additional manipulations. The emergency being with v74 which broke the native installer package of the Quest, users found themselves blocked. So I prioritized this development to solve the problem. I'm part of the PTC, it was annoying for users and for me.
Maybe you didn't read the description of my application well, the goal is for it to list the apk itself without having to go through a file picker.
