One of our beta users of Blueprint ( https://blueprint.io https://blueprint.io ), who incidentally also used to teach CS where I went to high school, signed up and sent a message saying that her students have been using App Inventor, that it was a great way to intro app development to those who have no programming background, but that it has the downsides of being Android-only and requiring a connected device for emulation, so she got a bunch of her students to sign up with us and they're having a blast. So, if you would like an iPhone alternative to App Inventor, give us a shot!
