Several recent applications have been released to remedy issues users have discovered with iOS 7’s moving wallpapers — namely, unintuitive changes in the ways iOS 7 resizes and positions photographs when used as wallpapers. Michael Belanger’s Fix My Wallpaper ($1) lets users zoom in and out on wallpaper photos, customize colors, and more. Wallpaper Fix ($1) from Bernhard Obereder promises quick resizing and positioning; this app locked up repeatedly during brief testing on an iPad Air. Another wallpaper resizing app is Brijit Sheelia’s Wallax ($1). All of the apps enable you to get a better sense of how an image will appear on the iOS device’s Lock and/or Home Screens, but one may have specific features that appeal to you.
