The app has been re-listed, we'll continue to monitor this over the next few hours.

Our team have identified an issue where the Luno app is not available on the Apple App Store. This will affect updates as well as new installs - we're working with Apple to see this resolved as quickly as possible.
The app will still function as normal but updates won't be available for iOS until the app is re-listed.
