Why i bought PS TOUCH if it does not save or share?...
I know this is an old post, but updating it, so someone else might find it useful. The ui is highly non-intuitive, so the steps are:
1. Click on the first icon on the top.
2. Select save to gallery.
3. Now select the project from the background! Yes, with the dialog open, you have to select the project.
4. Next you can note direct the type and click ok to save.
