Honestly, your success throws me for a loop—it's the exact opposite of what I've encountered. Every teacher I speak with objects to the very idea of paying for software—without even seeing the app. In another comment, I wrote this about Bingo Card Creator vs. Knack: I think the difference is that he's providing something teachers already use, need, and look for, as opposed to a "new" kind of software solution. (Online gradebooks aren't that new, but they still are not in use by the majority of teachers.) I really wonder if the difference is just in what we're selling. If I understand your product correctly, you offer instructional materials teachers have been using for a long time: customized cards to play bingo. This is something teachers are familiar with. As I mentioned in the post, teachers already buy classroom materials like pencils, letter charts, and decorations. They've been buying these for years and actually enjoy buying them. Bingo cards are a familiar need and expense. However teachers do not, generally speaking, regularly use software, much less pay for it every month. The concept of paying for an online gradebook is foreign, regardless of what the software looks like. If you don't mind, I'll send you an email to follow up. I'd really like to continue discussing.
