You get free usability testing of, and feedback about, your website/web-app, here:

  https://usability.testing.exchange

This is a side project where you'll learn about problems people encounter with your website/app, and what makes them confused. Then you can improve your website/app.

Normally, you get back as much testing & feedback as you give to others. However, I and some freelancers want to promote UTX. Therefore, you do not need to do any testing yourself in exchange, right now. (But you can if you want and it's fun :-)). So you can submit your website & get UX testing and feedback for free & no work.

How is it different from other free feedback exchange websites? — It's focus is usability testing, rather than giving advice & suggestions. And you can choose how much UX testing & feedback you want, about your own project: Do more UX testing yourself + write more detailed feedback to others —> you'll get more UX testing & feedback back, yourself — about as much as you gave (counted in the total sum of Math.log(the-length-of-each-feedback)).

All thoughts and feedback is welcome
