Apple’s price rises follow a dramatic fall in the value of the pound.

Mac and iOS apps from the UK App Store are set to rise in price by almost 25% this week to reflect the collapse of the pound following the vote to leave the European Union. Similar price increases are expected to hit other Apple stores, including the iTunes Store for music downloads, reports the Guardian.

The new prices reflect the changing value of the pound against the dollar. An app that costs $0.99 in the US used to cost £0.79 in the UK, but will now rise to £0.99.

Apple told app developers about the changes in an email, saying that “when foreign exchange rates or taxation changes, we sometimes need to update prices on the App Store”. The new prices will roll out over the next seven days.

Since Britain’s vote to leave the European Union, the value of the pound has fallen by 18.5% against the US dollar. Apple has already changed other British prices since the Brexit vote, launching its latest line of Macs with a 20% price rise in October.
