Unfortunately, the saving of projects is not a feature supported by this version of the app.
In order to access past DuoPix pictures that you may have created from your phone, you need to have actively saved it to your camera roll or DuoPix album (if option is selected under Settings). The autosaving of “finished” DuoPix photos is not a feature we support in this version.
We are looking into adding these two features to a future version of the app. Stay tuned.
