As part of the Adobe Creative Cloud Photoshop Photography Program, iPad owners have access to Lightroom mobile on iPad as well as Lightroom 5 and Photoshop CC on the desktop for a $9.99 subscription fee per month. Otherwise, users can freely download the app if it's not under the said program. The mobile version is available now for iPad 2 and later for iOS7 from the App Store. For Mac and Windows users, it requires the Lightroom 5.4.
