GPSmyCity

GPSmyCity provides a mobile application offering self-guided walking tours in over 1,500 cities worldwide. Users can select from various pre-designed city walks or create their own custom routes, with the app providing offline maps and turn-by-turn GPS navigation to explore points of interest.

GPSmyCity offers self-guided walking tours in numerous cities, which aligns with the 'themed-campaign-selection' and 'location-based-quests' features, as users choose specific city walks and follow routes to points of interest. The app also provides 'interactive-map-navigation' with turn-by-turn directions. However, it lacks explicit gamification elements like points, badges, or leaderboards, which are central to Wonderwise's 'leaderboard-rewards-system' and 'photo-wildlife-environmental-challenges'.
