You can also export the app settings from the iPad and then import into another device. That should carry along all of your engines and lash-ups.
Edit: I just tried this to see if it would work and I successfully exported all my engines from the iPad app and then imported them on an Android phone. After I exported it I shared to email, emailed it to myself, then clicked on it on my other device in its email app. Easy, peasy, george and weezy.
