I launched ChainCal back in late January, but I recently redesigned the app so I built a new site to promote it.
I'm not much of a marketer so I was hoping to get some constructive feedback from the HN community, having plenty of experience with this.
The site likely won't work well in old browsers at the moment since it uses a lot of CSS3.
Thanks!
However, maybe it's because of my monitor colours but everything looks pretty faint with the minimalist theme. I can't really see the various tasks that you've picked as samples. Also, personally, I prefer if you would tell me step by step what the app does instead of me having to wait for the animations to run through them step by step. However, I'm a technical user and I may not be your target audience.
Also, if you're looking to promote this app via your website, I'd recommend you have something that works well in most browsers so you can reach out to a larger audience.
Good luck!
