I think the difference is explained by the structure of my landing page. The iOS link is most prominent at the top, but the Android link requires some reading.

I'm going to update the Power 20 site to give equal airtime to iOS and Android.

Android sales have actually recently outpaced iOS sales because I'm able to iterate on the app's name more frequently in Android. I can find out which titles work faster on Android. With iOS, one must submit a new app every time they change the name. Crazy.

Just commented above, I'd love to know whether those modifications change results but based on my prior experience I highly doubt it.

Yeah, it's alarming to hear that even with millions of apps, you're seeing such a huge difference between iOS and Android sales. I'm going to change my future development plans if this is the reality for everyone.

Ya I've actually dropped Android support moving forward. Here's some more data on the stark differences in revenue:

I'm confused; where is the difference in revenue coming from if you're selling the same product to the same number of people on each platform?

Oh now I see the confusion. No the cut is about the same, it's the platform itself as in its users. I don't know what it is but I suppose they just tend to spend money and click ads less. I can't pinpoint the exact reason but many other developers have experienced the same trend.

Exactly where you just stated yourself... the platform.

As in, Google takes a bigger cut?

No, both Apple and Google take 30%.

I've written about this before on HN - it really is a Android vs iOS thing. I have identical apps on both stores both with millions of users. Android consistently generates 1/3 or less revenue as iOS.
