For #2, do you have any suggestions of other things that would work well on the home page?
And for #3, I went into detail on use cases/specific problems that we solve here: https://www.classpager.com/more -- Are you suggesting some of that be moved to the front page, or are you saying that the hook there is still unclear/not compelling?
Actually, you could solve #2 and #3 very easily by moving some of that material onto the homepage. Personally, I'd go with a simple, clean cut demo video. "Meet Martha...Martha is a high school teacher. But..." etc. and then later on in the video describe everything you put into pictures in more detail. Keep the graphic and diagrams though, in case users like those more than the video. And between those two, you'd get rid of a lot of white space hanging around. As for explaining it, the hook is very compelling and clear if you put one or both of those onto the homepage. Because the homepage as it stands now gives a basic idea of what the tech can do, but no examples of why what it does is useful. Having a teacher say, "Remember class is in room 142 today!" via text broadcast is more compelling for teachers than the comparatively less descriptive graphic you have on the homepage right now.
