Apps How to use MIT App Inventor 2

[Daniel Fernandes]

Hi
I have been making robots for the past three months and wanted to make my own apps to control them

I tried MIT App Inventor 2 but I can't understand the blocks

I know a bit of C codes so if there is any dev. tool that uses C language

Thanks in advance
