Here’s a quick list of questions I will ask the user while they are going through the prototype. I’m keeping it simple, as these people don’t understand UX. I also won’t be using all these questions just a few.

Before they start

• What do you think this app is for?
• What would you expect to do here?

During tasks

• What are you trying to do right now?
• What are you looking for?
• What would you expect to happen when you tap that?

After each task

• Was anything confusing?
• Did anything feel difficult or slow?
• Was there anything you expected but didn’t see?

Overall feedback

• How did the app feel to use?
• What did you like?
• What would you change?
• Would you use something like this?
