For my latest app, which is free with in-app purchase area unlocks...

Google Play: 10 times the amount of downloads than Apple Store

Apple Store: 2.5 times the income of Google Play.

Reviews on Google Play frequently mention how everything should be unlocked for free. Apple reviews seem to focus more on what extra content they would like to see.

Piracy on my paid apps seemed to be way, way higher on Android.

Have you tried switching to the ads model on Android (like suggested by your app's Android feedback/reviews)? I am curious if that would increase your revenue from Android users and somewhat lower piracy?

I've always been uncomfortable with the idea of advertising to children directly in an app.

Good for you as a parent I don’t allow my children to use apps with adverts. If the app is free with ads we buy the ad-free version or it’s a no go.

What if the developer has an app where the benefit of the app is to get users out of the app as soon as possible. For example, I have an app that helps me copy magnet links on my iPhone. I never spend more than two seconds in the app every time.

This is definitely an interesting data point that might support the ideas that a) walled gardens with DRM reduce piracy and b) iPhone owners tend to spend more.

Since kids tend to have more time than money, I'd also expect games/apps they use to have a higher degree of piracy, at least when it is relatively easy.
