As far as I know, Sizzy is the most known app to test responsiveness. As a paid user I really like all the features but whenever I open Sizzy to test my apps, my MacBook Pro overheats and basically everything gets frozen. After testing Responsively I can tell you all that it lacks some cool features and some final touching but it's definitely way faster than Sizzy and that's what I loved so...
