title: Free and Paid App, does it have to be 2 seperate app?
body: <p>I am integrating ads in my android app, but a thought came up, do I need to create a free and paid app, one with ads and locked features whilst another one with unlocked features, and I also need help on a tutorial to add in app purchases, all tutorials I keep finding advise me to first upload my app to google play, is that the only way? how do i fix bugs if I begin by uploading my app?</p>
