So this may be an odd question or may be one that has been asked but i couldn't find it when searching so ill ask it here. I have a class in my college that requires i have an RF remote to answer questions with. To put it into context, we have 500 people in our lecture class, and instead of handing out individual papers that have the questions on them, our instructor projects them onto the screen and then we use the clickers to answer. So is there an app that would make it possible for me to do this on my phone or no? Im running on a Samsung Stratosphere that has not been rooted...yet. Anyways, any info would be great, thanks.
