Save your money - very buggy
If you want to use the collage with more than a few pictures you’ll have to unlock those layouts. That’d be fine if the app worked!
When clicking Preview (which is required before clicking Save) the layout that you have just worked on becomes messed up. You cannot easily swap pictures that have been added, must be removed and then re-added. When swapping between layouts don’t expect your photos to go back to where they were.
You can’t resize the window.
Even after paying for the additional layouts, never could get the save working succesfully. I ended up taking screenshots so that I could use it. :-(
