Cool.
Now show me the part where it says Apple takes 15% or 30% from every purchase on the store
in addition to the $99/year that the developer pays.
Because they do. And they have since 2008.
And the Google Play Store does too.
You may think Apple and Google
shouldn't take 15% or 30% from every purchase. Well I don't know what to tell you.
It seems silly to keep having to explain how the App Store works even though it's operated this way for 14 years. But I'll say it again one more time.
Free apps:
$99/year membership fee
Distribute all the free apps you want for no additional cost
Paid apps, or apps with IAP:
$99/year membership fee
15% or 30% commission on every app or IAP sold
Seems simple to me...
