I like the relative simplicity of this app development tool, and I’m sure that it could do a decent job for:
- building simpler app ideas
- building prototypes – particularly useful for testing the flow of your app
- teaching the basic principles of app development
However, I suspect that Android App Inventor would be considered incompetent beyond a certain level of complexity of requirement.
I spent 20 minutes or so playing with Android App Inventor, and downloaded the app to see my experiments appear on my phone. Although it appears to be fairly simple to use, I will need to spend more time familiarising myself with it in order to use it for prototyping.
