Hi @Anonymous ,
Do you want to create a questionnaire inside PowerApps like using MS Form?
If yes, you can do it.
I did a simple test on my side for your reference. Assume that:
1. The entered answers will be saved into a SP list by clicking a submit button.
2. User can see his result after submit his answers
So I create an app with 10 dropdown controls(With Yes/No choice).

Then add a button, rename it to “Submit”. Set its OnSelect to formula like below(save these 10 answers into a one-column collection):
Patch(listname,Defaults(listname),{Question1:Dropdown1.Selected.Value,.....});
ClearCollect(Result1,{Value:Dropdown1.Selected.Value},{Value:Dropdown1_1.Selected.Value},{Value:Dropdown1_2.Selected.Value},{Value:Dropdown1_3.Selected.Value},
{Value:Dropdown1_4.Selected.Value},{Value:Dropdown1_5.Selected.Value},{Value:Dropdown1_6.Selected.Value},{Value:Dropdown1_7.Selected.Value},
{Value:Dropdown1_8.Selected.Value},{Value:Dropdown1_9.Selected.Value});
Set(varY,CountRows(Filter(Result1,Value="Yes")));
For displaying the result, I add a label under the button and set its to below. So, If answers with yes equals/more than 5, it will display as “High”:
If(varY>=5,"High",varY<5&&varY>=1,"medium",varY=0,"low")

Besides, you can also add below formula into the button, so after you submit your answers, you will receive a prompt message:
Notify("Your answers has a result with: "& If(varY>=5,"High",varY<5&&varY>=1,"medium",varY=0,"low"));

For more about Notify function, you can refer to this article:
