Yes, we will definitely be making video tutorials for the iPad app - I just wanted to wait until we had most of the tweaks and design changes worked out first.
For backing up the data you have already entered in the iPad app, we strongly recommend uploading to a Dropbox account (via Admin > sync). You should always keep a copy of your data somewhere outside your device, just in case it is lost or malfunctions.
Don't worry - we won't yank the beta version from you, but when we release the final version this summer, the beta version won't receive any more updates. The lesson plans and records you have already entered in the beta version will easily transfer over to the paid version.
