The application uses a mobile phone’s GPS to find nearby deals and also lets users plug in their Zip codes to get the coupons.

Users can also browse deals in any city or choose deals tailored to their interests.

You don’t have to be a T-Mobile customer to use the app, which is free through the Android Market.
