This is the qr code i made for the app i had made with Mit App Inventor with lots of trouble but i was able to figure it out with the help of a few friends. The qr code was made with QR Code Generator i have worked on it for a few months now with trying to figure out how to use mit app, inventor build a app, and make sure it works nicely  with all this you can scan the qr code and it will let you check out my app.
