I don't want to transfer purchases from device to iTunes because that would take forever. Plus I'm going to be cleaning out my phone down to one page of app [dreaming ]. I know we can transfer single apps from iTunes to device but I'm not interested in that. I just want to transfer 1 or 10 apps manually. Is this even possible? If not, it should be an obvious option. Do I really need to delete all the apps I don't want on my device first, then transfer all purchase to iTunes? If so that's a big cluster f#ck. Reason for solution: I want to do a clean restore to improve performance of device. Therefore I just want to transfer a few apps that have internal data backups like chat app history or financial data etc that is stored in iCloud. Is it better just to make sure vital app data is backed up in iCloud, do a fresh restore to iOS 11 then re-download those few apps? Sometimes things can get sketchy though and not sync properly between app server and iCloud. That's why I want to manually transfer a few apps from device to iTunes. Is is better to rely on iCloud or transfer of apps to iTunes to reliably save app data? EDIT: from what I've read this is not possible. And even if it were possible, no app data is backed up to iTunes. We need a 3rd party explorers utility for that or just reply on iCloud or App company's server for back up.
