Good, but content lacks depth – TourPal Travel Guide with Tour Maps & Trip Planner Review

I did one of the Berlin walking tours. The content is accurate in directions and well produced, but I wish there was more of it. Would be nice to have different topics on each point of interest (history, present day, architecture, etc), and be able to listen to as much or as little as I like. I payed $6 or so for the tour which had maybe 30 minutes of produced audio content. I don't feel it's a great value for the money compared to other produced content, say, a TV show or podcast. I enjoyed the tour though, and would recommend it if you are ok with the few downsides.
