Can I have paid apps on more than one device and how?
This must have been answered before, but I wasn't sure how to search for it, so apologies in advance...
I have several Apple devices and I want to put the paid apps I have on one device on another as well. I would have assumed this was possible - perhaps via iTunes, but I can't see how to do it.
It doesn't seem to make any difference whether I restore from a previous device's backup (to the new device), or create a 'new' device.
So, for example, I have bought Air Display for my iPad mk1 and I now want to put it on my iPad mini as well. (I don't want to use them simultaneously.) The iPad mini is set up as a new device, so hasn't been restored from the iPad mk1's backup.
As another example, I have an iPhone 5 that I restored from an iPhone 4s backup. Most things were installed, but none of the paid apps came across and they're not listed in my iTunes library.
Do I have to buy them all again? Or am I doing something wrong? I would have assumed that they would be stored with my account details (all the devices are set up with the same Apple id).
Many thanks.
