I suspect it would be the same with Lightroom, and in any event I don't want to pay for that. I don't have a desktop computer and my entry level laptop (which I bought months ago just for word processing and light browsing) takes a second or two just to adjust exposure with GIMP. I'm not used to having no right-click or File menu.) I'd rather work on my laptop with the 28' external monitor.
(BTW, I first started playing with SnapSeed on my iPad but the screen is just too small.
