We have built remote controlled car with my kids - complete design from start to finish with 3d printed wheels and cogs, arm based IC, Bluetooth connection and when needing the remote, we did binary based transmission over BT in the app inventor (AI). The difference between say ecllipse, intellij or AI was very small and it (AI) provided the "yes we can" solution. So while I agree that for quality app one uses different tools, it's nice to have things like this. What is really missing in AI is native support for network communication.
