Ask HN: Feedback from Heroku users?

During the process of building a few Heroku apps I found that the provided scheduler addon, while very useful, was somewhat limited. So, I scratched the itch and built a more flexible scheduler supporting full cron expressions and one-time jobs.

I'm trying to publish it as an addon and would love to have some input from other Heroku users on what need, if any, they have for something like this? Also, please let me know if you want to check it out in alpha (email is in profile).

Thanks HN
