Another new app of mine has been launch recently at https://play.google.com/store/apps/details?id=com.piggystudio.cartoonphoto. The new app is able to transform any photo with cartoon effect and similar to cartoon drawing.
The cartoon photo app has configurable cartoon sensitivity to create your desire effect based on your settings by increasing sensitivity or line size. As soon as you are satisfy with the result, just click done icon to complete the creation of cartoon photo.
The cartoon photo app also comes with other basic photo effect such as sepia, monochrome, grayscale, soft light, and others. Feel free to try out the app for yourself.
