We used a program called MIT appinventor which is a program that allows us to make our own apps and put them online so other people can view them.

It is a open program that runs in the web and just requires a google account

Here is the link to the website: MIT App Inventor

Here is a bit of what the program looks like

There is also a way to use live debugging to be able to test our app 

Before the live debugging we woul dhave to download a new verson of our app every time we wanted to test something

If you want to downlaod my app you can with this QR code:
