VoiceMap: Audio Tours & Guides

VoiceMap provides self-guided audio tours for various cities and destinations worldwide. These tours use GPS to automatically play stories and information as users explore, offering a way to learn about their surroundings at their own pace with offline map support.

VoiceMap offers self-guided audio tours that use GPS to trigger stories based on the user's location, aligning with 'Location-Based Quests'. It also provides an offline map for navigation, which matches 'Interactive Map Navigation'. However, it does not explicitly offer 'themed campaign selection' in the sense of adventure quests, nor does it have a 'leaderboard & rewards system' or 'photo, wildlife & environmental challenges'. Its focus is on storytelling and historical/cultural exploration rather than gamified adventure quests.
