I think this is an excellent app and its perfect for people who think visiting typical tourist destinations is an inauthentic experience but still want to see what the fuss is about. Its fairly easy to use after you play around with it a bit. I think that some simple improvements would be to include the approximate distance covered by the tour, not just the time, and to allow for a view a map of the whole trip while on it, not just the very next destination. Overall, Im super happy with this app and totally recommend that you get it! Ive used the "Fishermans Wharf" and "Cold, Grey, City" tours and plan on using the other SF ones if we have time. It gives you background info, provides photos and uses your GPS location to pause and restart the tour based on where you are. As someone who loves podcasts, especially those with a storytelling aspect, Detour is perfect.
