Using this as a teaching platform was my first reaction too. I don't think I would use it for anything production though without an option to export the app (database & source for my app). I would pay the listed monthly subscription fees in a heartbeat. That is a no brainer for the time this appears to save but I have learned the hard way too many times in the past on being locked into a platform for business crucial stuff. I would be fine even paying a one-time fee of few hundred dollars to be able to export my app if I need to. Simply for the peace of mind of not being locked in if something happens.
