that should result in more people willing to give us feedback.

But I find that there are a lot of unnecessary steps to get to the actual feedback - there is a welcome screen where the user needs to click/tap "Next" just to get to the page where the record button is. I think that a setup where everything is on one page would make a difference. It has been proven by testing that one page checkout increases conversion compared to multi-step processes where you lose people at every click. I don't see why the same wouldn't apply to feedback.

Could you provide an option to put everything on a single screen, i.e. when the user arrives to the page, they instantly see the Record button?

I love the concept and I think this would make it even better.
