Positive: - The idea of an app-guided self-exploration of a foreign city - The attractive price (compared to a booked city tour) - The presentation of many sights - Exciting puzzles and a lot of additional information about the respective place - The integration of Google Maps to the next place Negative: - The starting point of the tour is too far from the train station or bus parking lot where the visitor arrives (note: at least half an hour's walk away) - Puzzles via camera zoom are a nice idea, but hardly feasible Opportunities for improvement: - Adjust the starting point - Include addresses (tourist information, train station, bus parking lot, etc.) - Name prices for sights Conclusion: Can I recommend the scavenger hunt for Bruges? Definitely! The app is well made for the city, you see and learn a lot from it. And the price is cheap considering that.
