According to an email sent to developers, apps published in Australia, Indonesia and Sweden will have their prices hiked in response to changes in currency exchange rates.
App Store prices are set in tiers. In Australia the lowest cost apps are $1.29. The cheapest US apps are US$0.99. Applying current exchange rates (we used the XE currency app on iPhone for our checking) put the local pricing at $1.35.
Given the Australian dollar is tipped to lose some more value we would be surprised to see local pricing for apps jacked up to as much as $1.49 at the bottom level.
As Apple doesn’t change pricing in direct response to every move in exchange rates they need to take a financial position that covers them in the event of potential future falls.
We’ve contacted Apple for an official statement. Nothing has come through yet but we’ll provide further information as it comes to hand.
