While other editing apps have a spot removal function, they usually can only deal with a very small area of the image. TouchRetouch goes way beyond that, with powerful selection and predictive tools to remove larger objects for an image.

Features (from Google Play)

Select and remove unwanted shapes, objects, blemishes
Single-flick line removal
Brush and Lasso selections
Clone Stamp
Built-in tutorials

As with even the most powerful software, the success of automated corrections depends on the complexity of the image. TouchRetouch is a great tool and easily the best correction app I've come across.

Best used for:

  • Spot corrections
  • Object removals
