Hey @rrhover saw this and thought of you. You must be inundated with people wanting your time and there is a fine line between fan/user interaction that can boost brand value versus a time sink. This tool gets around that by scheduling and recording those interactions in your spare time. Pretty cool. I'm going to sign up for my book series.

This was recently launched by my publisher in London, John Wiley. This is, what we hope, will be a fundamental change to the way investment banks train their employees about quantitative finance. This book series is a niche product but will reduce the social cost of mismanaged risk.

I am using a few apps to force daily habits and one new habit I am trying to create is to take time out to notice the sunrise or sunset. With SunsetWX, I know in advance when one is coming and gives me that extra motivation to set aside time for that daily pause. Plus, they have never been wrong! I took the pic above from my apartment.

@rrhoover interesting monetization. Was this sponsored at the original local or does that stay with the awesome product hunt team?
