I wouldn't even say it's a design issue. More of an information issue.
If there's no demo available, I need (as a potential purchaser) quite a bit of information to know if it's worth risking my $$'s. I'd say some combination of screenshots/gifs or screencasts going through the program would be great. Or maybe more of a focus on the workflow, or maybe just expanding your features section to be illustrated with screenshots form the app showing how features are used.
Honestly, some of the best descriptions of the program are in App store reviews where it's compared to other distraction-free/markup writing environments.

Also, congratulations and good luck!
