Works fine once you get the hang of it. If you keep in mind that this is only for cropping, you’ll be good. The only thing I don’t like is that, since I use my finger to drag the reference points around, I can’t actually see the point I’m moving. My fingertip is too big. It takes some trial and error. It helps to watch the crop line move if you’re trying to get right angles. I also wish this had crop to shape, the way PowerPoint does. One more thing. It doesn’t automatically save the image you cropped. You have to tap the image and then it’ll ask to save it. Not intuitive. The other reviewer had a s—- fit because he didn’t figure that out.
