With the introduction of larger, more powerful iPads, Adobe are now considering the iPad as a serious photographers workflow tool. The July 2017 update to the mobile version of Lightroom, is a huge step forward toward providing a a powerful alternative to Lightroom on the desktop/laptop. This new release introduces a similar interface and set of tools between and Mobile and Desktop versions, though you will need to be a CC subscriber to unlock all the available functionality. There are still some capabilities within the desktop version of Lightroom that are not available in the Mobile. That said I will use Mobile for library management and basic edits - all of which can be done on the go given the iPad's mobility features.
