There are software sales situations when that makes sense, bespoke enterprise software etc. but not phone apos as far as I can tell.

Any idea on how many of those are low end devices sold to users who just want a phone and have no interest in the play store?

I just get the feeling that looking at averages of the entire platform in this instance can be misleading as there are different types of users.

The marketplace was also vastly different - when Apple was at its peak the market was physical, boxed copies had to be shipped to stores or via mail order. Now the respective stores give access to the entire market with one upload.

The other major differentiator is the number of users likely to download an app in the first place. Stats are very hard to get, but the general feel is iPhone users are much more likely to install apps, with a lot of Android users just buying the cheapest phone.

There's a lot of money in both markets though, so picking one is really a matter of where your company can ship first.

App Annie shows that of all revenue from paid app downloads, Apple accounts for 70% of it, which is up from 60% in 2014.
