It is great to note that the app interface is exactly the same as the interface that the students see when logging in to the site on their phone. Everything is laid out exactly the same way with the easy to follow instructions and the bright graphics to engage the users.
I logged in to my Kahoot account on my laptop and had a go at playing one of my quizzes in order to test out the whole user experience and it was flawless. It travelled through the questions and feedback pages smoothly and easily. Students who used the app to complete their quizzes would have exactly the same experience as a student who was logged on via any other device.
