We all use several devices: desktops, laptops, tablets, phones - depending on where we are and what we do. But we want to do the same thing the same way no matter what device we are using. Hence we need a DropBox Capture App for Apple iOS and iPadOS to annotate and share screen-shots and screen-recordings on our Apple iPhones and iPads with the same tool we use on our Apple iMacs and MacBooks. Does this make sense to you?
