The software features a sharing option through Dropbox. You can go ahead and create a new wallet and password and then use the Dropbox integration to sync the data. This feature needs to be used on the first device and then synced on the second one. This is the way the developer explained on its FAQ page.
I strongly recommend to read the information on the FAQ page to understand how to work with the program: http://beta.kuffs.co.uk/support/faqs/
