Hello there

I'm new here and don't understand how the iOS and Android games integrate into itch.  Could someone explain or point me to a post on this?  it seems if I download an iOS game it will launch in a browser.  What happens if I have purchased the game on iTunes - is there any link?

Thanks!

I'm not sure how iOS games work yet, but from my experience with developing an Android mobile game, it's as easy as downloading the .apk and sending it to your phone via adb or your preferred file transfer method. You can also directly download the file from your phone. But again yeah, not sure if it's the same for iOS. 

I also know that there are playstore integrations, a game page can have links to those.

My apologies, but could you elaborate a bit what do you mean by integration into itch? What are you trying to achieve? 

See that previous post I got from leafo:

You can reference the google play store on your page (assuming you have your game on both itch.io & the google store).  From itch you can download APKs straight from the site to your android phone/tablet and install the games that way.
