A navigational guide for tourists, the app is able to guide users whether he/she is in indoor(eg: Museum, galleries, aquariums) or outdoor. Similar to Google Maps, it must be able to show nearby landmarks (say maximum of 15 km radius) and update the distances as user approaches. Embed these contextual information into the phone's camera with augmented reality. User can pin their POI (point of interests) in the app. Looking for a developer who has experience in the fields of navigation and AR.
