I am looking for a developer to build a platform for creating Android and iPhone location based treasure hunt style apps. The user receives riddles in the form simulated phone calls and texts and must then enter the correct text or go to the correct geographic location. If the user solves the riddle either by entering the correct text or are in the correct location they will receive the next riddle. The app will have embedded maps that register correct geographic location with the phone’s GPS and work offline. I have an interactive prototype ready built with proto.io There will be two short embedded videos.
