[flatline-]

I've searched for the answer for days, but both Google and Apple haven't offered me anything concrete so far.

I was hoping to find someone here who could tell me whether in-app purchases done through iOS' StoreKit are bound to a minimum price. We are currently researching an app idea that would offer content for as low as 0.10 USD.

Also, I heard that Apple charges a 30% fee for all app purchases. Does this fee also apply to in-store purchases? We would also like to know to which extent we are free to choose the micro-payment processor of our liking, for all our in-app purchases.

Please excuse my ignorance, as I'm very new to iOS development. Any insights would be hugely appreciated.

Best, Ro

30% flat off everything that goes through digital distribution (what is "in-store purchasing"? Apple physical stores selling cardboard boxes of stuff, or the App Store?).

Have you looked through here?

I don't know about minimum in-app purchase price, but I seem to recall it being $0.99, same as for apps.

The minimum price for the country; $0.99 in the US, the equivalent elsewhere.

Apple takes 30% of all purchases that they handle; app purchase, in-app purchase, etc.
