Harddee's "Happy Star Rewards" app, and a few questions

Hi Everybody, This is my first forum post, and I'd much rather be reviewing this app. However, I'm having a problem, so I don't really feel qualified to fully review the Happy Star Rewards app. It is an app that apparently gives you rewards based on a random spin of a wheel after a specified number of check in's to your local Hardee's or Carl Jr.'s restaurant. (Free food got my attention). I was excited that 90% or more of the app was accessible, but I can't say if the wheel spinning is accessible or not. My local Hardee's restaurant is listed in the locator,, however when I attempt to check in, while sitting in the restaurant itself, I am repeatedly told that I must be inside the restaurant to check in. I have written the developer about this, but I have yet to get a response. I'm writing all of this here, not to make you feel sorry, or go ok, and? but to ask if any of the rest of you have tried this app? Did you have similar results? This is a free app, so I encourage you to try it if you haven't. I just searched in the app store for Hardee's. I will try to paste the app store link below.
