I have developed an application that sends messages to mobile within many more things you can do. My question is if I go up that application that I have to pay more for an application that sends messages. It's the same price for up an application in all cases?, I find few requirements on the rise in applications in the apple store.
Thanks and sorry for my bad English.
Are you talking about push notifications?
Apple don't charge developers to send push notifications. You pay your $99/year and 30% of your app's cost no matter what features you use.
If you're using a third party service to send out the notifications, that service might charge you, however.
