Apple has a number of restrictions for apps in their app store. One of these is that we adhere to their pricing tiers for content sold anywhere on our service (£0.99, £1.99, £2.99 etc). Having flexible control of pricing is how we offer the best value to our customers.
Apple also would also charge us much more than what we make on each transaction.
Therefore, we have taken the decision to not support purchase on iOS devices. We apologise that this means you’ll have to visit our website on iOS devices in order to purchase content or subscribe to Boosts. We’ve been working hard to ensure that the mobile website experience as good as that of the native app.
