I love this app. I happen to live in a densely populated city where there are more local Groupons for me to trip over, so I trigger quite a few. I did travel to Michigan on the road and double checked and sometimes I didn’t see any. So if you don’t see any, I checked with the developer and for now you can go to your Settings, select GrouponTripWire and change the slider bar named Groupon Offer Range (0.2-10 Kilometers) about 5 miles. Set this to the max and see if there are any offers there. The developer also told me that they are coming out with a release that automatically scales it to the nearest offer if there aren’t any within the default range. So don’t get discouraged if you are too far away from a big city. However, if you are in a big city don’t do the above, you map will be overrun with all the icons, especially in Chicago. Love this app, easy peasy.
