Last Thursday Apple released the free Photoshop.com Mobile app, and it already has about 2,400 ratings and 675 reviews. The app lets you do basic editing such as crop, rotate, and flip photos. You can adjust exposure, saturation, and tint. Special effects include Vibrant, Pop, Border, Warm Vintage, Rainbow, and more. Most of the reviews are enthusiastic. The negative ones are disappointed that it doesn't have more of the features of the desktop version. Some people are never satisfied. You can also create a Photoshop.com account and store up to 2GB of photos for free.
