Thanks for all the feedback. That all makes sense. I’ll try and get an APK on github releases in a second repo (until I open source the app repo). Then test how that works with the different app stores. It might break updates once I change the repo though. But I’ll see what works 👍🏼 

 So I tested Optainium and it worked fine. Do people usually copy/paste a github url themselves when installing a new app? 

 I either C/P, or there's a search function in the app that works on GitHub. Thanks for checking out Obtainium!🙂 

 I sent you a DM re Zapstore
