I'm not really sure that there is anything I might do on Product Hunt that would improve Screenful's odds of success. However, if it meets the guidelines, this might make a good 'Show HN'. Show HN guidelines: https://news.ycombinator.com/showhn.html
On the other hand, 'Show HN' is more about getting feedback than Product Hunt. Good luck.
