You’ll need to have iOS 12.3 and later to run Lightroom iOS 5.0.
Batch editing, which was already available on Android, has now come to iOS – copy edit settings from one image and paste them to many.
First, copy edit settings from one photo – click on the three-dot icon (#1 below), choose Copy Settings (#2), select which settings you want to copy (#3), drilling down into individual sections if needed (#4), then tap on the checkmark (#5) to complete the copying.
Next, select multiple images and paste: go to grid view, tap on the three dots (#1 below), choose Select (#2), then tap on images to select them. Next, don’t tap on Done (this gets me all the time!) – instead tap on Paste (#4 at the bottom). Depending on how many images you selected, pasting may take a while.
