Up to now, Lightroom mobile (for iPad and/or iPhone) was only available for those who entered the subsciption plan (and hence are now paying monthly or yearly for Lightroom CC). I don't want to be a cow that will be milked for the rest of my time on earth (I'm still considering emigrating, by the way
), and I will stick with Adobe only as long as they sell the programs I like, and so I have upgraded to LR6.
Well... now you can get Lightroom for free from the App store (through iTunes and, hence, for your Apple mobile device). I have downloaded the app and will be looking into it, but for serious postprocessing, I will always rely on my iMac. But LR mobile might be a nice gadget for some of us.
