The price of App Store apps and in-app purchases will increase in all countries and territories that use the euro on October 5. The euro's weakness against the U.S. dollar is the reason for the increases.
In addition, prices of apps and in-app purchases will increase in many countries.
Apple gives developers preset tiers that they can price their app at, and these tiers will increase for the euro next month. The maximum tier will increase from 999 to 1,199, while tier one will increase from 0 99 to 1.19.
There is more information about the App Store price tiers on Apple's website. The price tier of the app can be adjusted to match the increases.
The price increases don't affect auto-renewable subscription.
