We arrived at the starting point of the Truro tour and opened the app as instructed. We answered the quiz questions and then set off to the next destination. We felt it would have been useful if there was a 'first time users guide which sets out what to do step by step. It might also be good if the app suggests a 'next destination ' for those to use who are less confident in what they are doing. Overall, it was a great way to see parts of the city that we wouldn't otherwise have seen and to give us something extra to do rather than wandering aimlessly. We certainly stayed there longer than we would have done otherwise.
