It's comparable to Google's charge and only slightly more expensive than other merchant providers.

I still consider it quite extortionate however considering app devs are adding to the ecosystem and potentially driving sales.

You can install APKs on Android. The Play store isn't necessary. On iOS, however, you have no option but to use Apple's AppStore.

which merchant accounts are charging that? last i saw it was typically a transaction fee of ~35¢ and around a 2-3% fee on the rest.
