I made a little side project where you can get feedback by 20 fresh eyeballs for your website or app. And even by 40 fresh eye balls. They will tell you why they wouldn't use your service and what's ugly.
What do you think, would you give it a try?
P.S: Private Emails are much much harsher than the videos, there I tell you why I wouldn't use your product and all the things I find ugly.
Have a nice day
