I wish I’d read reviews before I bought. Hope this helps someone else. The advantage of Theo tour is that it allows you to get across a wide-spread city with fewer stops than a city bus.
But the commentary is minimal: a sentence or
two. Don’t expect to learn anything.
The buses can come as far apart as 20 minutes and, while the tour’s app shows you where buses are, you will have to search for a small icon on a small map. There is no real-time updating. So if you are a time-maximizer, you will find this frustrating.
The stops are also not available on Google maps so you need to use their app to find them. They are marked with a small red post, not an actual bus stop and in busy areas this can be hard to spot.
So, for me, the one advantage to this transport was fewer stops than a city bus and two
routes that cover the city.
