A review tool, not a feedback platform
Usersnap is built to collect feedback from the people using your product: widgets, surveys, ratings and announcements, with analysis tools on top. That's a broad platform, priced accordingly.
ClientTweak is narrower. It's for the review stage of a web project: a client approving a homepage, a designer checking spacing on staging, QA flagging a broken button before launch. Reviewers open a link, click the element and comment.
