The app allows Chinese customers to search the night sky to find special constellations hidden amongst the actual ones while panning and tilting there phone synced with the actual  star positions.

When the discover a special constellation (each appearing at specific times in the night to sync with the current offers) they win a discount coupon or a free prize. On top of that three 'Lucky Shooting Stars' would pass by at random times in random places and catching those would amount to a bigger cash prize.

There was also a geo-locator to guide you to the closest McDonalds to claim your winnings
