iOS Universal Photography
Pressure sensitive drawing comes to the iPad, iPhone and iPod Touch! Sketchtasy is a basic drawing app that reacts to your touch. The harder you press, the thicker the line will be that you draw!
Sketchtasy also allows pictures from the photo album to be loaded and used as a backdrop to the drawing. This makes it possible to trace over a photo and then take it away to reveal your drawing.
Please note that the app will provide better results if you hold your iPad, iPhone or iPod Touch in your hand when drawing rather than placing it on a flat surface because the accelerometer is used to detect the touch pressure.
Support for the Retina 4 inch screen
