Apple recently let app developers know that the prices of apps and in-app purchases will go up in a number of countries to compensate for variations in the currency rate.

Specifically, iOS users from Israel, Canada, New Zealand, Singapore, South Africa, Mexico and Russia will pay more when they visit the Apple Store.

The price for subscription services for countries on the list will get adjusted as well. Apple clients should know that in South Africa and Russia they must subscribe manually for the subscription services, at the new price.

There are no subscription services available in Israel at the moment, meaning the country's users will be unaffected.

Subscribers from the other four countries will get a notification before the current subscription runs out, allowing them to cancel their service or make a new one at the actualized rate.

According to an email sent by Apple to developers worldwide, other minor modifications to tariffs are in store.

Canada and New Zealand will see the introduction of low price tiers, namely Alternate Price Tier A and Alternate Prier Tier B. The offers help developers work with smaller items, such as In-App Purchases. Markets from developing countries have very affordable prices for alternate tiers at the equivalent of 20 cents USD.

Customers of the App Store will pay the same amount of money in Romania, although the country changes its VAT from 24% to 20%. The difference will not go into Apple's accounts, which means that developers will have the most to gain from the tax reduction.

Even before the App Store increased its prices to match the new currency rates, Apple's online app market was way ahead of competition when looking at gross income.

For example, the App Store's revenue was as much as 80 percent larger than Google's Play Store in the third quarter of 2015. The profitable trend will immensely benefit Apple Inc., who had a 70 percent advantage at the end of the second quarter.

The current wave of price increases is effective in the next 72 hours, which should encourage some of the readers to stock up on apps and in-app purchases right now.
