Android App Inventor tutoriales

Hello friends, today I have an interesting beginners tutorial for App Inventor and it is not about a game. It is about how to make a shopping list app in app inventor. 
This tutorial covers some interesting points.
The idea is simple , for this shopping list app , we have 3 screens, in one we create the shopping list using textbox and tinyDB then this list "creates" in screen2 a group of CHECKBOXES, these check boxes are the ones we use while buying at the market, then when we check the checkboxes jeje they make 2 lists for a shopping list report and pass this report to Screen3 , the report says which item we buy and wich ones we couldn't get. 
Also I add an extra feauture, I add a simple calculator to help us while buying to know how much are we spending. unfortunately this calculator part is NOT in this tutorial. SO if you want to SEE part 2 please LIKE LIKE LIKE LIKE the video and please SHARE SHARE SHARE it and let me know you are interested in part 02 :( jeje have a nice weekend guys
