It seems that the free version does not do what is stated: send the newly created wallpaper to the iPhone.

After editing a photo, the only option available to me was to email the wallpaper or to save it. The 'send to iPhone' option was grayed out.

Looking at the advantage list for the 'pro' version, it says 'iPhone integration'. It seems the free version does not do as advertised. Instead if you really want to easily send the wallpaper to the iPhone, you have to pay $14.95 for the pro version.

No thanks. I'll use an image editor and move the image to the phone myself.

I deeply resent programs that advertise themselves as 'free' then prove to be 'crippleware'.
