Hey HN. Just wanted to share something I built in a few weekends. I guess this is more geared towards product/marketers, but we've built it to be very developer friendly.
Uselio is dirt simple and powerful user feedback that you can hook into any interaction or feature on your website (rather than just leaving it on the bottom of every page). Plug it into a few features and you can see exactly how users are responding to every feature, as well as the overall NPS/CPAS of your App.
Let me know your thoughts. :) It's still buggy, but it works! Happy to offer a 25% discount to all of you... just message me in-app or here.
