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