Apple will soon be increasing the prices of paid apps and in-app purchases in a handful of countries due to exchange rate changes. App Stores affected by the change will be those in Canada, Israel, Mexico, New Zealand, Russia, Singapore, and South Africa. Those using in-app subscriptions in Russia and South Africa will need to resubscribe.

These sorts of adjustments are not uncommon. The changes in pricing are expected to take place across these countries in the next 72 hours, according to an email sent to developers by Apple.

While this is disappointing, it’s not surprising. The Canadian dollar in particular has dropped like a stone in the past few months.
