What everyone is saying about this app is true: its full of features, easy to use, fast and versatile.
The biggest problem is the fact that youre always working on a low-res (ie blurry) version of the image, not with the full resolution. This has been done to speed up calculations while the image is edited, but it makes many filters and effects useless.
How can you use a Sharpen or UnsharpMask filter when youre working with a blurry preview of the image? How can you be sure of the result of a Blur filter if the image is already blurry? You cant crop an image precisely either.
Agreed, the app is only 0.99$ and is otherwise very well done, but you cant do any serious work with it.
