XnView Photo Fx for iOS
Between Ian & I, we've got reviews of a plethora of free photo effects apps from the developer of XnView. Whether you use Windows, Mac, iOS, or Android, there's an app for that! I could also use your help with a new Android section of the site. If you work with graphics or photos on an Android mobile device, please tell us about the apps you use in our new Android App user reviews section.
