What Adobe is now calling "Lightroom CC" (not to be confused with "Lightroom Classic CC" is the program they used to call "Lightroom Mobile".
I used to use this very infrequently from my iPad... but found it to be extremely limited. For one, they resampled images to a smaller size (not sure if they still do that) ... it could not open true un-adjusted RAW files direct from the camera. Also they now have desktop clients for it (previously it was just a mobile app).
I might imagine that in the future they'll add to it's capabilities... but the current version is far too limited to be useful. In fact it's so limited... that I feel like the free Apple "Photos" app that Apple includes on all iPhones, iPads, and Macs is at least as powerful (and that's not meant to be a compliment to Apple Photos... it's more of a ding on Adobe "Lightroom CC".) While Apple's Photos software isn't my favorite... at least it's free. Adobe actually expects us to pay for that level of functionality.
My greater concern is that they slapped the label "Classic" on the original "Lightroom CC" ... which smacks of "that's the old legacy version that we plan to support for a limited time and eventually dump." -- no, they didn't actually say that... but that's how I interpret the use of the word "classic". And if that's the case... I need to find some new software.
Possibly Adobe expects to continue to improve their new "Lightroom CC" ... but today's version doesn't come close to having feature parity with the "Classic" version.
