Feel like cropping pictures? iZoom gets the job done. This little application lets you adjust a photo and focus on a specific area, to then crop out what you don't want.
iZoom comes with almost a dozen preset sizes, which for most people will be just what they need. These go from iPod Photo to thumbnail, desktop background or email portrait. Select one of the presets, load in your photo and adjust it. All you then need to do is crop.
You can also create your own custom cropping profile thanks to the size and quality tools at the bottom left.
These, and that is my general gripe with the program, are fairly limited. iZoom lets you crop photos but nothing more. The editing features are restricted and there aren't any more settings you can play on.
The applications is slightly limited, yet iZoom makes for a quick cropping tool.
