The fact that most apps are ad-based is what drove me away from the app store entirely on Android. It's impossible to tell what's actually free, and it's hard to find honest apps that you can just pay for instead of dealing with ads or microtransactions.

So I would never have seen your app. I was already driven out of the "ecosystem". I wonder how many others are like me -- fully willing to pay, but so disgusted by the app scene that we aren't even there anymore.
