Photo Blender is an iOS app for your iPhone, iPad or iPod that combines photos horizontally using gradient blending at the seams where they are joined.
Photo Blender is a simple app that merely joins photos vertically, horizontally or in 2D by either blending or abutting them at their edges. Photos can be prepped in the Aviary image editor, as can the blended output. The app supports up to 16 photos.
