Apps in iTunes will transfer to your iPhone, iPad, iPod touch or iPad Pro. What we were hoping for was to be able to transfer from device back to iTunes.
I've got used to just downloading to iTunes on my PC and transferring to my devices. It's probably only a problem for people like myself who don't want to download the same app several times as I have more than one device, plus I keep a back up of all my iTunes content so do want the apps on computer. At one time my broadband was limited so when I had phone data I would download the apps to the phone and transfer to PC (iTunes) to enable me to then update my other devices, although now on unlimited broadband, I still prefer to just do the download once. Also I was experiencing dreadful slowness of apps downloading on my computer and being able to download on a device and transfer to computer and then to other devices would have been great (it was taking sometimes 20 minutes to download even a very small app to computer).
I believe Apple are not going to revert to being able to transfer app purchases back to computer.
