Here are some of the capabilities of this app:

• Crop, Rotate, Flip
• Several effects like Rainbow etc
• Changing Hue, Tint, Saturation
• Artistic Sketch and many more...

I just tried this app on my Iphone. Its cool.

Using these features is very simple, just sliding your finger from left-right will work the trick. For example, for changing the Tint, just slide from left to right to show differnt tints and apply.
