To add images, simply tap the folder button on the left. You can choose to add existing photos, a new camera photo, or a text caption.
In Photo mode, which is enabled by default, you can Move, Rotate, or Resize images directly using multi-touch manipulation.
In Blending mode, which you can enable using the switch in the bottom right, multi-touch lets you fine tune the amount of blending applied to an individual image.
In Canvas mode, you can manipulate or zoom in and out of the overall background canvas for the scene. This is useful when working with a populated canvas that is larger than your view area. By touching the background canvas while in other modes, you can still modify it directly without entering this mode.
To Save An Image, tap the folder icon and you will have the option to save your completed work to the device's photo library.
To Change The Blending Style, tap and hold an image to summon its editor.
To Change The Background Color, tap the settings icon and choose Canvas Settings.
To Change The Canvas Size, tap the settings icon and choose Canvas Settings. Exported images will be saved at this resolution.
To Change The Order of Images, double-tap an image to bring it forward.
To Freeze an Item, tap the settings icon then select Freeze. The object can no longer be edited until you Thaw it (using the same settings menu.)
To Edit Text Captions, tap and hold the text to summon its editor.
To Remove Items, tap the trash can icon.
That's all there is to it! Enjoy!
