Best one I've tried so far – Photo Cut Out Editor Review

Only a couple of improvements need to be made: A tool to draw straight lines. Many objects to cut out have straight lines (such as product photos). It is hard to draw a straight line with your finger on the cutout edge. A straight line tool would help a lot. Or even a pen tool as in Photoshop. Saving an image should be simpler. The "Share" button takes you to the FX page, or to an ad to unlock features. It is not like saving in other programs. Otherwise it's a nice app and the scribble tool works well.
