thanks @kwdinc. Here's a bit about Hearties:
Hearties is a augmented reality game with hidden rewards. Me and my friend Jomis do research in the field of AR and created this app for fun. So far we have hidden about 100 items in 20 cities. Most treasures are hidden behind an image and a location. You will get clues to get find and loot them. You have to perform some activities, solve puzzles, or race to get to them. We would love your feedback, let us know at twitter:@heartiesapp or info@hearties.co.
Good luck and have fun.
