Mac and iPad

I was just wondering if I buy Scrivener for my mac, will I also have to purchase it again to use on my iPad Pro and iPhone? Or will one subscription cover me for all three devices?


There is no subscription, but the iOS apps needs to be bought from the App Store, while Mac apps can be bought from the Mac App Store or directly from developers. There is no connection between the two different App Stores.
So yes, you need to buy the iOS version if you want to use it in an iOS device.
